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??
