We have y=f(x), and get the inverse by uing the first function and solving it for x and get x=g(y). (F and g are different functions.) Then we swap the name of x and y and we get y=g(x).(adsbygoogle = window.adsbygoogle || []).push({});

Buw why can we do this when we want to find the inverse functions? If we got y=f(x) and want to find the inverse we take g(f(x))=x. But how is this related to the first thing I did?
