5.6.15. Let f: A → B be an arbitrary function. (a) Prove that if f is a bijection (and hence invertible), then f-'(f(x)) = x for all æ E A, and f(f-'(x)) = x for all x E B. (b) Conversely, show that if there is a function g: B → A, satisfying g(f(x)) = x for all x € A, and f(g(x)) = x for all x E B, then f is a bijection, and f = g.
