Suppose that is f a function and f^{-1} is the inverse of f. If f(3) = 4, f(5) = 1, and f(2) = 5, evaluate $f(5) + f^{-1}(4)$.

If \(f(x) = y\), for 2 numbers x and y, then \(f^{-1}(y)=x\).

Now that we know that, we can find the value of \(f^{-1}(4)\), which is just 3.

Also, \(f(5) =1\) (pretty straightforward).

Can you take it from there?
