一、深挖细查,突破解题的瓶颈例1已知函数y=f(x)有反函数,定义:若对给定的实数a(a≠0),函数y=f(x+a)与y=f-1(x+a)互为反函数,则称y=f(x)满足“a和性质”
First, digging, breaking the bottleneck problem solving Example 1 Known function y = f (x) has an inverse function, the definition: If the given real a (a ≠ 0), the function y = f ) And y = f-1 (x + a) each other as an inverse function, then said y = f (x)
