So h of negative 14, well, this is going to be equal to negative two. Once again, they are inverses of each other. So h of negative 14 is equal to negative negative two. And once again, I just swapped these two around. That's what the inverse function will do. If you're mapping from, if f goes from negative two to negative 14, h is going to go from negative 14 back to negative two. So now we want to evaluate f prime of negative two.
