Problem 45E

Indicate which of the functions in the referenced exercise are one-to-one correspondences. For each function that is a one-to-one correspondence, find the inverse function.Exercisea. Define f: Z ? Z by the rule f(n) = 2n, for all integers n.(i) Is f one-to-one? Prove or give a counterexample.(ii) Is f onto? Prove or give a counterexample.________________b. Let 2Z denote the set of all even integers. That is, 2Z = {n ? Z | n = 2k, for some integer k}. Define h: Z ? 2Z by the rule h(n) = 2n, for all integers n. Is h onto? Prove or give a counterexample.
