专题04 函数的定义域、值域的求法【热点聚焦与扩展】函数的定义域作为函数的要素之一，是研究函数的基础，也是高考的热点.函数的值域也是高考中的一个重要考点，并且值域问题通常会渗透在各类题目之中，成为解题过程的一部分.所以在掌握定义域求法的基础上，掌握一些求值域的基本方法，当需要求函数的取值范围时便可抓住解析式的特点，寻找对应的方法从容解决.（一）函数的定义域1.求函数定义域的主要依据是：①分式的分母不能为零；②偶次方根的被开方式其值非负；③对数式中真数大于零，底数大于零且不等于1.2.①若()y f x =的定义域为(),a b ，则不等式()a g x b <<的解集即为函数()()y f g x =的定义域； ②若()()y f g x =的定义域为(),a b ，则函数()g x 在(),a b 上的的值域即为函数()y f x =的定义域． 3.对于分段函数知道自变量求函数值或者知道函数值求自变量的问题，应依据已知条件准确找出利用哪一段求解.4.与定义域有关的几类问题第一类是给出函数的解析式，这时函数的定义域是使解析式有意义的自变量的取值范围；第二类是实际问题或几何问题，此时除要考虑解析式有意义外，还应考虑使实际问题或几何问题有意义； 第三类是不给出函数的解析式，而由()f x 的定义域确定函数)]([x g f 的定义域或由)]([x g f 的定义域确定函数()f x 的定义域．第四类是已知函数的定义域，求参数范围问题，常转化为恒成立问题来解决． （二）函数的值域1.利用函数的单调性:若)(x f 是],[b a 上的单调增(减)函数,则)(a f ,)(b f 分别是)(x f 在区间],[b a 上取得最小(大)值,最大(小)值.2.利用配方法:形如2(0)y ax bx c a =++≠型,用此种方法,注意自变量x 的范围. 3.利用三角函数的有界性,如sin [1,1],x ∈-cos [1,1]x ∈-.4.利用“分离常数”法:形如y=ax bcx d++ 或2ax bx e y cx d ++=+ (c a ,至少有一个不为零)的函数,求其值域可用此法. 一般地，① ax by cx d+=+：换元→分离常数→反比例函数模型② 2ax bx cy dx e++=+：换元→分离常数→a y x x =±模型③ 2dx ey ax bx c+=++：同时除以分子：21y ax bx c dx e=+++→②的模型 ④ 22ax bx cy dx ex f++=++：分离常数→③的模型共同点：让分式的分子变为常数5.利用换元法: 在高中阶段，与指对数，三角函数相关的常见的复合函数分为两种： ① ()()(),log ,sin f x a y ay f x y f x ===⎡⎤⎡⎤⎣⎦⎣⎦：此类问题通常以指对，三角作为主要结构，在求值域时可先确定()f x 的范围，再求出函数的范围.② ()()(),log ,sin xa y f a y f x y f x ===：此类函数的解析式会充斥的大量括号里的项，所以可利用换元将解析式转为()y f t =的形式，然后求值域即可.③形如y ax b =+,可用此法求其值域. 6.利用基本不等式法:7.导数法:利用导数与函数的连续性求图复杂函数的极值和最值,然后求出值域8.分段函数的函数值时，应根据所给自变量值的大小选择相应的解析式求解，有时每段交替使用求值．若给出函数值或函数值的范围求自变量值或自变量的取值范围，应根据每一段的解析式分别求解，但要注意检验所求自变量值域范围是否符合相应段的自变量的取值范围．数形结合法也可很方便的计算值域. 9.由判别式法来判断函数的值域时，若原函数的定义域不是实数集时，应综合函数的定义域，将扩大的部 分剔除.10.数形结合法：即作出函数的图象，通过观察曲线所覆盖函数值的区域确定值域，以下函数常会考虑进行数形结合.（1）()f x 的函数值为多个函数中函数值的最大值或最小值，此时需将多个函数作于同一坐标系中，然后确定靠下（或靠上）的部分为该()f x 函数的图象，从而利用图象求得函数的值域.（2）函数的解析式具备一定的几何含义，需作图并与解析几何中的相关知识进行联系，数形结合求得值域，如：分式→直线的斜率；被开方数为平方和的根式→两点间距离公式.（三）常见函数的值域：在处理常见函数的值域时，通常可以通过数形结合，利用函数图像将值域解出，熟练处理常见函数的值域也便于将复杂的解析式通过变形与换元向常见函数进行化归.（1）一次函数（y kx b =+）：一次函数为单调函数，图像为一条直线，所以可利用边界点来确定值域. （2）二次函数（2y ax bx c =++），给定区间.二次函数的图像为抛物线，通常可进行配方确定函数的对称轴，然后利用图像进行求解.（关键点：①抛物线开口方向，②顶点是否在区间内）. （3）反比例函数：1y x=（1）图像关于原点中心对称（2）当,0x y →+∞→ ，当,0x y →-∞→. （4）对勾函数：()0ay x a x=+> ① 解析式特点：x 的系数为1；0a >注：因为此类函数的值域与a 相关，求a 的值时要先保证x 的系数为1，再去确定a 的值 例：42y x x =+，并不能直接确定4a =，而是先要变形为22y x x ⎛⎫=+ ⎪⎝⎭，再求得2a =② 极值点：x x ==③ 极值点坐标：(,-④ 定义域：()(),00,-∞+∞⑤ 自然定义域下的值域：(),2,a ⎡-∞-+∞⎣（5）函数：()0ay x a x=-> 注意与对勾函数进行对比① 解析式特点：x 的系数为1；0a >② 函数的零点：x =③ 值域：R（5）指数函数（xy a =）：其函数图像分为1a >与01a <<两种情况，可根据图像求得值域，在自然定义域下的值域为()0,+∞（6）对数函数（log a y x =）其函数图像分为1a >与01a <<两种情况，可根据图像求得值域，在自然定义域下的值域为()0,+∞【经典例题】例1【2017山东理】设函数A ，函数y=ln(1-x)的定义域为B ,则A B ⋂=（ ）（A ）（1,2） （B ）⎤⎦(1,2 （C ）（-2,1） （D ）[-2,1)例2【2018（ ）D.例3【2018届河南省中原名校（即豫南九校）高三第六次质量考评】已知函数()()2231,3{2,3x a x a x f x a x --++≤=>（0a >且1a ≠），若()fx 有最小值，则实数a 的取值范围是（ ）A. 50,6⎛⎤ ⎥⎝⎦B. 51,4⎛⎫ ⎪⎝⎭C. 550,1,64⎛⎤⎛⎤⋃ ⎥⎥⎝⎦⎝⎦D.

But what about The Woggle-Bug , The Marvelous Land of Oz , The TikTok Man of Oz, and The Patchwork Man of Oz? These four novels, plus nine more, were sequels（续篇）to one of the most popular children’s books of all time.Baum’s life story isn’t like any of the characters in Oz at all. Instead, he was raised in a wealthy household with eight other brothers and sisters. His father was an oil man that became rich in the productive fields of Pennsylvania. Although he was frequently ill in his childhood, he never stopped daydreaming. When he was a teenager, Baum’s father bought him a cheap printing press and soon Baum was publishing a journal that even had paid advertising. As he got older, Baum produced more journals about the things he was interested in, such as stamp collecting and raising a special kind of chicken.Baum had a lifelong love of the theater and would always take parts in plays. In 1880, his father built him a theater, where Baum wrote, acted, and gathered other actors for his plays. Two years later, during the production of Baum’s ironically-titled （具有讽刺意味的标题）Matches, the theater caught fire and burnt to the ground, causing most of Baum’s plays to be destroyed. Later, Baum focused on writing and hit it big with The Wonderful Wizard of Oz. After that, Oz was turned into a play and Baum’s dreams had finally come true. For the rest of his life, Baum swore off writing sequels to the Oz series, but kids wrote him letters, so he continued. Baum’s career was highly distinguished and he even predicted the existence of TVs, computers, and advertising on clothing more than 100 years beforethey existed.4. How many sequels are there to The Wonderful Wizard of Oz?A. A dozen.B. Four.C. Nine.D. Thirteen.5. Which of the following is TRUE of Baum’s childhood?A. Baum was the only child in his family.B. Baum was born into a very poor family.C. Baum had a wide range of interests and hobbies.D. Baum began publishing cartoons in his teens.6. Why does the passage refer to the play Matches as ironically-titled?A. It was a strange name for a play.B. It was meant to fire up readers against the government.C. It was a total failure because people didn’t like it.D. The play was produced when an accidental fire happened.7. Which of the following would best describe Baum’s role as a writer?A. Realistic.B. Confident.C. Imaginative.D. Energetic.CA name is supposed to last a lifetime, so picking a name for your baby doesn’t seem like something you would want to base on current trends. The general trend in baby naming these days is all about originality. Classic, traditional names like the ones given to the characters of most Hollywood movies over the past 30 years are on their way out. Instead of common and familiar names, new parents want unique and even strange ones.This can mean reaching a bit further into the past for names that were typical a few generations or more ago but are uncommon now. Old-fashioned names have a strangeness that many new parents judge to be cool. Need another option for your special little boy or girl? Try a foreign name because a name from another language is sure to draw attention and might give your child an attractive image within your own culture. After all, if you look beyond your own language, there are an incredible number of charming names to choose from. Another option is to use a last name as a first name. Parents who want to honor someone important or someone famous like a politician, artist, or writer might tend to give the famous surname to their child as a first name. Hence parents that like music or sports have been choosing names like Jackson or Jordan to honor their favorite people. Celebrities（名人）have always liked to stand out from the crowd, and they are making sure their children do as well, with names like Moon Unit, Apple, and Jermajesty. Just remember, a baby’s name is theirs for life, so choose wisely and avoid picking a name that will likely result in endless jokes and nicknames for the first 20 years of his or her life.8. What is the first paragraph mainly about?A. The popularity of original baby names.B. Current events influencing naming babies.C. Hollywood celebrities prefer classic names.D. Picking out names for children isn’t so important.9. What does the expression “on their way out” mean?A. Losing popularity.B. Drawing attention.C. Causing dissatisfaction.D. Gaining force.10. In regard to baby naming, what does the author think is a good idea?A. Naming from only the parents’ mother tongue.B. Naming children after someone important.C. Using names of foreign streets, cities or countries.D. Using strange name making children instantly popular.11. What can he inferred from the final sentence?A. Babies named Jackson will have great musical talent.B. Parents can choose their child’s name and nickname.C. Names from jokes are becoming more popular now.D. Proper names won’t bring discomfort when they are growing up.DLong ago in ancient Greece, people knew that the worst scars left by terrible events were psychological as well as physical. They knew that people that survived terrifying situations were disturbed by nightmares, flashbacks, illogical anger. But it was not until the time of the Vietnam War that psychiatrists began to formally study Post-Traumatic （创伤的）Stress Disorder （PTSD）. Although many people have suffered traumatic events as victims of crimes, wars, or natural disasters, most return to a normal state of mental health. Some people, however, are troubled by their memories from these experiences for the rest of their lives.Tile reason for this is because of real changes in the sufferers’ brains. PTSD patients usually show a low level of cortisol in their brains. Cortisol helps people to return to their normal, unstressed state, but rather than relaxing after trauma, sufferers of PTSD stay in their stressed state. Furthermore, research shows that the hippocampuses （海马神经）of Vietnam veterans （老兵）suffering from PTSD are unusually small. In the brain, the hippocampus controls the amygdala, which is linked to fear and the memory of fear. A smaller hippocampus may mean the amygdala’s influence is too strong, giving rise to unreasonable responses to stress.While earlier generations of soldiers and disaster victims simply had to live with the problem, sufferers nowadays have been helped through treatments developed by doctors since the 1970s. The most successful methods to reduce symptoms is to use cognitive therapy（认知疗法）, which is avoiding and reducing negative thought patterns, and drugs. In particular, MDMA, which has been tested because its positive effect on moods, lets patients discuss their memories without triggering their fear response.While there may never be a complete cure for PTSD, it is now widely recognized as a problem. Military personnel and disaster survivors are screened for symptoms, and those who need help are no longer ignored.12. Which one of the following is NOT mentioned as a symptom of PTSD?A. Bad dreams.B. Poor concentration.C. Flashbacks.D. Anger.13. According to the passage, PTSD can be caused by _______.A. genetic disorderB. a smaller hippocampusC. high levels of cortisol in the brainD. an abnormal state of mind14. What is the best way to cure PTSD?A. Brain surgery.B. Therapy for those heading to war.C. The reduction of negative thoughts.D. Never allow a person to be involved in a traumatic event.15. What can be inferred from the passage?A. PTSD has been around as long as wars.B. PTSD is caused by only one thing.C. Most sufferers are civilians, not members of the military.D. Veterans of the Vietnam War drew attention to the issue.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

He wasn’t quite sure what he was looking for until he ran across some turtle hatchlings.He didn’t know it was turtle. Fortunately enough he got the right person to ask and he got motivated. That person was Nkindi, a staff member at the Watamu Conservation project who later invited him tovolunteer on the project. He later left his accounting job and fully devoted himself into the world of sea turtles. Now，he runs and spends his time nursing critically endangered sea turtles back to health.Sea turtles have been around for nearly 110 million years and are now considered highly endangered. Their preservation rests on activities of conservationists such as Kiponda as these turtles face numerous threats and signs of their extinction in the next 50 years.Local fishermen traditionally catch them to supplement their own low catch rates and sell them for their oil. As changes are made to accommodate more hotels for tourists, there is less available beach land for turtle nesting.Kiponda’s passion has now spread t o his community, changing their attitude towards sea life preservation with his “by-catch rele ase programme.”Through this program, fishermen are now paid for returning turtles accidentally caught in their fishing nets. The healthy ones are tagged and released into the marine park while he takes care of sick and injured turtles back to health.Before the launch of pioneering spirit like this, turtles caught by fishermen were used for their meat and their oil extracted (提炼) for its medicinal properties.“Rel easing the turtle back into the ocean is a very good feeling, like, you feel like you’ve done something concrete and I guess everybody would love to do that...so I gue ss it’s unique work.”24. What was Fikiri Kiponda’s dream job according to the text?A. An accountant.B. A marine conservationist.C. A guide to the Watamu Conservation Project.D. An advocate for turtles.25. What may be the main threat to the turtles?A. The rising sea level.B. Being caught by tourists.C. Overdevelopment in the tourism.D. The reduction in their nesting place.26. Which of the following words can best describe Fikiri Kiponda?A. Energetic but conservative.B. Enthusiastic and caring.C. Arbitrary but considerate.D. Ambitious and knowledgeable.27. Which of the following can be the best title for the text?A. The man saving endangered sea turtles.B. An unique job of protecting sea turtles.C. A pioneer project protecting sea animals.D. The current situation faced by sea turtles.CAn autonomous vehicle designed for making local commerce deliveries was unveiled by Nuro. The vehicle is about the height of an SW but far narrower than a typical car. The electric car features four exterior compartments (暗格) — two on each side — to hold separate deliveries. Each compartment can be tailored to a specific use, such as cooking a pizza or refrigerating a package.“We ca n use self-driving technology to deliver anything, anytime, anywhere for basically all local goods and services,” Nuro co-founder Dave Ferguson s aid. “Consumers used to be okay with two-week paid shipping. It became two-week free delivery, followed by one week, two days, and the same day. Now same-day delivery i sn’t fast enough for some customers.”Nuro isn’t alone in building robots for local comm erce deliveries. Earlier this month, Toyota, a Japanese car company, unveiled a concept vehicle that could be used for package delivery. A handful of startups — including Starship Technologies, Marble and Dispatch — are testing small robots for deliveries on sidewalks.Nuro’s vehicle will likely face legal hurdles. Fully autonomous vehicles without a test driver aren’t legal in California today, and many companies have shifted testing to states where regulators are more welcoming of autonomous vehicles, such as Arizona.Nu ro expects to face fewer challenges because it doesn’t carry passengers. Nuro’s narrow size may also be helpful when navigating streets and avoiding pe destrians. The vehicle isn’t equipped with any special features to communicate with pedestrians or other road users. Some companies have tested and patented solutions such as digital screens that signal the car’s next move. Ferguson said his team conducted studies and found that such techniques could confuse people. Nuro believes ifs better to make sure the car performs predictably, so that human drivers know what to expect from it.“We feel by creating this new technology that’s going to enable this last mile delivery, we’re going tobe creating new markets and doing things that previously weren’t possible,”Ferguson said. “This is not swapping out Jobs with robots. It’s creating new markets. There will definitely be new employment opportunities.”28. What is the main characteristic of the Nuro’s self-driving vehicle?A. It can cook delicious meals for customers.B. It is a pioneer in the field of self-driving vehicles.C. It is fur narrower and higher than other autonomous ones.D. Its deliveries can be transported in the special compartment.29. Which can best replace the underlined word “hurdles” in Paragraph 4?A. Breakthrough.B. Dilemma.C. Restriction.D. Protection.30. Wh y is the Nuro’s vehicle not equipped with communicating features?A. Its digital screens often break down.B. People may be puzzled at the features.C. The features have not been developed.D. Its performance is usually hard to predict.31. What can we infer about Ferguson’s opinion on this new technology?A. Beneficial.B. Challenging.C. Controversial.D. Ambiguous.DWhile there are a few ways to make use of your old smartphone, one of the better ways is to convert into a dash cam (行车记录仪) that you can use on your bicycle. With the camera, you can record your rides, which is especially helpful if you are involved in a crash with another vehicle.To use your smartphone as a dash cam on your bike, you will need to make sure it is properly secured to your bike. To do this correctly, you must take two strips of heavy-duty Velcro (a kind of cloth used as fastening) along with two pipe Clamps (管夹) and a flat corner brace (角撑) to properly attach it. You will start by attaching the comer brace to your smartphone.Next, attach a Velcro strip to your phoned back. You will put the second strip on the end of the bracecomer and cut any extra Velcro off and away from the brace. By using heavy-duty Velcro, you shouldn’t have to worry about the camera brace must be attached to the bicycle directly.Take two pipe clamps so you can attach the part of the corner brace so the phone can be held up and used. The pipe clamps must be positioned near the center of the handlebar, which will enable you to get a better picture when videotaping.To run a dash cam app on your old phone, you will just need to download a dash cam app onto the old phone. You will then just start the app at any time you head out on the road. There is always the chance of flaws, but you will be giving yourself a way to protect yourself in a friendly, eco-friendly manner that is much less expensive than purchasing a dash cam.32. What is the purpose of building a dash cam on your bike?A. To make full use of an old smartphone.B. To record the scenery while travelling.C. To reduce an unexpected crash on the road.D. To avoid unnecessary arguments in an accident.33. What does the underlined word “it” in Par agraph 2 refer to?A. The bike.B. The pipe clamp.C. The smartphone.D. The flat comer brace.34. What can we learn about a Velcro strip?A. It will fix the camera firmly.B. It is better to keep it as long as possible.C. It is important for the flat comer brace.D. It is best put in the center of the smartphone.35. What can be inferred about the DIY dash cam from the last paragraph?A. It is a perfect alternative to a purchased one.B. It is beneficial to environment in some way.C. It is a much more demanding job for the user.D. It makes its owner friendly to other people.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
