函数方程问题一般较为抽象,由于没有统一的分类和解法,加上解题过程涉及函数性质和多种数学思想方法,要求学生有较强的逻辑思维能力与灵活转化本领,因此,函数方程问题是高考复习中的一个难点.本文试通过题组教学,引导学生归纳、总结函数方程问题的求解规律,激发学生学习积极性, The function equation problem is generally more abstract, because there is no unified classification and solution, plus the problem-solving process involves the nature of the function and a variety of mathematical thinking methods, requiring students to have a strong ability of logical thinking and flexible transformation skills, therefore, the function equation problem is A difficult point in the review of the college entrance examination. This article tries to pass the group teaching, guide students to induction, summarize the law of the function equation problem, stimulate student enthusiasm,
