Answer:

Yes. A function is invertible if and only if the function is bijective. ... A bijection f with domain X (indicated by f: X → Y in functional notation) also defines a relation starting in Y and going to X. Properties (3) and (4) of a bijection say that this inverse relation is a function with domain Y.
