函数是高中数学的重要内容,对于高一同学来说,解决有关函数问题时会遇到一定的困难,主要原因往往在于不善于从题设条件联想相关的知识,寻求解决问题的突破口.事实上,从函数的基础知识出发,有效转化问题的条件,就可以探寻到解决问题的方法,也就能形成解题的基本思路.下面以一道例题来说明. The function is an important part of high school mathematics. For Grade One students, there are certain difficulties in solving the related function problems. The main reason is often that they are not good at associating relevant knowledge from the questions and seeking breakthroughs to solve problems. Starting from the basic knowledge of the function and effectively transforming the conditions of the problem, we can find a solution to the problem, and we can also form the basic idea of ​​solving the problem. Here is an example to illustrate.
