| 摘 要： | 二次函数是中学数学的重要内容之一,和它相关的内容,如:二次方程、二次不等式、二次三项式及二次函数的图像,构成了一个体系,称之为"二次式系列";本文主要在以下三个方面对这些题目的解法进行探讨:(一)求参数的范围;(二)根的存在情况的判别;(三)求最大、最小值;通过以上的讨论,以期提高中学生对此类题目的解题方法和解题技巧。

| Abstract: | Quadratic Function is one of the important parts of middle school teaching, its relevant things, such as Quadratic Equation, Quadratic Inequality, Quadratic Trinomial and Graph of the Quadratic Function, constitute a whole system which is called quadratic serials. This paper is mainly to discuss the solutions to these mathematical problems in the following three aspects: 1. How to get the parameter range; 2. How to confirm the existence of the root;3. How to calculate the maximum and the minimum value. Gene... |
