复合函数的定义和性质相对于基本初等函数比较难理解.因此,复合函数题型对于高中生来说既是一个难点,也是一个易错点.也正因如此,复合函数问题成为近几年高考数学的一个重要考点.为了更好地帮助学生掌握复合函数问题的解法,加深对知识的理解.本文从复合函数的结构入手,将这类问题的典型错解进行归类、分析,并提出相应的解题策略.
The definition and nature of the composite function is relatively difficult to understand relative to the basic elementary function, therefore, the complex function problem type is not only a difficult point but also an easy-to-miss point for high school students. An important test site.In order to better help students grasp the solution to the problem of complex functions and deepen their understanding of knowledge.This article starts with the structure of complex functions and classifies and analyzes the typical mistakes of such problems and puts forward the corresponding solutions Tactics.
