    For problem 1, the proof is obvious by definition. If f\in C^n(\Omega) then f^\prime, f^{\prime\prime}, \ldots, f^{(n)} are all continuous. Let g = f'. Now, what are f^{\prime\prime}, \ldots, f^{(n)} in terms of g? What does that tell you about g's differentiability class?

    I have no ideas for problems 2-4.
