(a) Explain why the function f(x) = e is not injective (one-to-one) on its natural
domain.
(b) Find the largest possible domain A, where all elements of A are non-negative and
f: A → R, f(x)
ez is injective.
(c) Find a codomain B such that f: A → B, f(x) = e¤´ is surjective.
(d) Show that g: B → A, g(x) = VIn x is the inverse of f. Why is f-1(x) # -VIn x?
