5. Let f : [0, 1] → R be twice differentiable. Suppose that the line segment joining the points (0, f(0)) and (1, f(1)) intersects the graph of f at a point (a, f(a)), where 0 < a < 1. Then, A. there exists z E [0, 1] such that f'(z) = 0 B. there exists z E [0, 1] such that f"(2) = |f(1) – f(0)| C. there exists z e [0, 1] such that f"(2) = f(1) – f(0) D there exists zE [0 11 such that f"(-) = 0
