数学高二升高三练习题
数学高二升高三练习题第一题:已知函数 f(x) = x^2 - 4x + 3,求以下各题的解:1. 求函数 f(x) 的极值点和极值;2. 求函数 f(x) 的零点;3. 求函数 f(x) 在定义域内的单调性和区间;4. 求函数 f(x) 的图像。
解答:1. 首先,求函数 f(x) 的导数 f'(x) = 2x - 4。
令 f'(x) = 0,可得 2x - 4 = 0,解得 x = 2。
所以函数 f(x) 在 x = 2 处取得极小值。
将 x = 2 代入函数 f(x),可得 f(2) = (2)^2 - 4(2) + 3 = -1。
所以函数f(x) 的极小值为 -1。
2. 求函数 f(x) 的零点,即求解方程 f(x) = 0。
将函数 f(x) 带入,得到x^2 - 4x + 3 = 0。
通过配方法,将方程转化为 (x - 1)(x - 3) = 0,解得 x = 1 或 x = 3。
所以函数 f(x) 的零点为 x = 1 或 x = 3。
3. 求函数 f(x) 在定义域内的单调性和区间。
(1)对于定义域内的 x < 1,将 x = 0 代入函数 f(x),得到 f(0) = 0^2 - 4(0) + 3 = 3。
再将 x = 2 代入函数 f(x),得到 f(2) = (2)^2 - 4(2) + 3 = -1。
所以在区间 (0, 2) 内,函数 f(x) 是单调递减的。
(2)对于定义域内的 1 < x < 3,将 x = 2 代入函数 f(x),得到 f(2) = (2)^2 - 4(2) + 3 = -1。
再将 x = 4 代入函数 f(x),得到 f(4) = (4)^2 - 4(4) + 3 = 3。
所以在区间 (2, 4) 内,函数 f(x) 是单调递增的。
(3)对于定义域内的 x > 3,将 x = 4 代入函数 f(x),得到 f(4) = (4)^2 - 4(4) + 3 = 3。

And it’s human 24 to feel a bit uncomfortable a bout the unknown.Most of our fears about dealing with new people come from 25 about ourselves.

There are all sorts of tricks at play each time we reach out for that particular brand(品牌) of product on the shelf. Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged (包装) in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver.When some kind of pain killer was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective . Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm.The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to. It is believed that the better-known companies spend, on average,70 per cent of the total cost of the product itself on packaging!The most successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote (推销) their goods, came to the conclusion: ―Any fool can make soap, but it takes a genius(天才) to sell it.‖41.Which of the following may trick a shopper into buying a product according to the text?A.The cost of its package.B.The price of the product.C.The colour of its package.D.The brand name of the product.42.The underlined part ―the colours turned the customers off‖(in Para.3 ) means that the colours_____________.A.attracted the customers stronglyB.had weak effects on the customersC.tricked the customers into shoppingD.caused the customers to lose interest43.Which of the following is the key to the success in product sales?A.The way to promote goods.B.The discovery of a genius.C.The team to produce a good product.D.The brand name used by successful producers.44.According to the passage, which of the following statement is true?Making soap is so easy that any fool in the world can make it.Greens, yellows or silver are considered to be healthy colours.25 years ago, the founder of Pears soap was a pretty girl herself.The size of a product can have an effect on the shoppers.45.Which of the following would be the best title for this text?A.Choice of Good ProductsB.Disadvantages of ProductsC.Effect of Packaging on ShoppingD.Brand Names and Shopping Tricks高二升高三英语入学测试单选1-5BBCAB 6-10BBBCD 11-15AACAB语法填空(共10小题;每小题1.5分,满分15分)16.答案为 skillfully。
