(c) Give two (essentially different) examples of functions f : (a; b) → R, which are differentiable, but whose derivative is not continuous. (d) Suppose f: (a; b) → R is differentiable and its derivative f' : (a; b) → R is continuous. Suppose also that f'(xo) # 0 for some ro € (a; b). Conclude that there exists an interval (a1; b1) around ro and an in- terval (c; d) around f(ro), such that f : (a1;b1) → (c; d) is one-to-one and onto (i.e., bijection).
