在高中数学复习中,会遇到求函数解析式的一类题,这里是指已知y=f〔g(x)〕或y=f〔f(x)〕,求f(x).是否有一套有效的方法可循呢?回答是肯定的.这类题在现行的高中数学教科书中几乎没有,但它与课本上的函数这一内容关系密切,并具有一定的规律性,故就有一些有效的解题方法.根据本人的学习心得整理如下: 请看高中数学《代数》第一册(甲种本)
In the review of high school mathematics, you will encounter a class of questions that require analytical expressions of functions. Here, it is known that y=f[g(x)] or y=f[f(x)], and find f(x). Is there an effective way to follow? The answer is yes. Such questions are almost absent in the current high school mathematics textbooks, but they are closely related to the content of the textbooks and have a certain degree of regularity. Some effective problem-solving methods. According to my learning experience are organized as follows: See high school mathematics “Algebra” Volume 1 (A type of this)
