The next two questions pertain to the function f, whose graph is given below: 12. For the function f, I. f' ( - 3) > 0 "10 TY II. f' (0) 0 on the interval (-5, -4) II. f'(x) is constant on the interval (4, 6) III. f' is not defined at all points of the interval (1, 5) (A) I only (B) II only (C) III only (D) I and II (E) II and
