Question

(a) If f '(x) = g '(x) for all x and f(11) = g(11), then f(x) = g(x).



(b) If f is differentiable and f(15) < f(16), then there is a number c, with 15 < c < 16, such that f '(c) > 0.



(c) If f '(x) = g '(x) for all x in (a, b), then there is a constant K such that f(x) = g(x) + K on (a, b).
