5. Suppose that f: R → R is a continuously differentiable function (of class C¹) and that there is a positive number c> 0 such that f'(x) > c VER Prove that f(x) ≥ f(0) + cx Prove that f is surjective. That is, f(R) = R. Prove that f is a diffeomorphism from R onto R. That is, f-¹ exists and is differentiable. (Hint: One can consider Mean Value Theorem, Intermediate Value Theorem and Inverse Function Theorem.) if x ≥ 0 and f(x) ≤ f(0) + cx if x ≤ 0
