函数的单调性和奇偶性是研究函数的两大“法宝”,在学习中要充分挖掘其潜在的解题功能,下面从几个方面谈谈其在解题中的应用.
The monotonicity and parity of functions are the two “magic weapons” of the study function. In the course of learning, we must fully explore its potential problem-solving function. We will talk about its application in solving problems from several aspects.
