二次函数是初中所学的知识,但高中继续深入学习,在高考中经常涉及,是中学阶段的一个重要函数.通常要求学生掌握二次函数的概念、解析式、图像及性质,能利用二次函数研究一元二次方程的实根分布条件,能求二次函数的区间最值.一般来说,高考所出的题型包括以下三类:1.求二次函数的解析式
The quadratic function is the knowledge that junior high school learns, but the high school continues to study deeply, often involves in the college entrance examination, is an important function in the middle school stage. Usually asks the student to grasp the concept, analytical form, image and nature of the quadratic function, can use two The subfunctions study the real root distribution conditions of the unary quadratic equation, and can find the interval maximum value of the quadratic function. In general, the question types of the college entrance examination include the following three categories: 1. Solve the analytical function of the quadratic function
