函数是中学数学的重点内容,而抽象函数问题又是函数内容的难点之一.抽象函数是指没有给出具体的函数解析式或图像,但给出了函数满足的一部分性质或运算法则.由于此类函数问题
Function is one of the most important parts in middle school mathematics, and the problem of abstract function is one of the difficulties of function.Abstract function means that no specific function or image is given, but some properties or algorithms of function satisfaction are given. Such a function problem
