(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f(22)=9 and f^-1(13)=7

find f^-1(9) and f(7)

(given that these are 1-1 functions)

2. Relevant equations

What does this mean as the have not given the equations they used to find the values, i know inverse function is the function that can find the opposite of the original function.

3. The attempt at a solution

Can someone help me see how to start to work out this problem??
