Question 1091007: Let f(x)=x+2 and g(x)=x/3. Also denote the inverses to these functions as f^{-1} and g^{-1}. Compute f(g^{-1}(f^{-1}(f^{-1}(g(f(19)))))). Answer by greenestamps(13200) (Show Source):
You can put this solution on YOUR website! There is nothing complicated about this except the notation. You just need to make sure you start with the innermost parentheses -- which means you work from right to left to evaluate the given expression.
As for the notation, let me use F and G for the inverses of the two given functions.
