I'm having trouble understanding this problem.

(6 points) Consider the function f (z) = x? -4x # 5 on the interval 0, 4). Verify that this function satisfies the three hypotheses of Rolle's Theorem on the inverval. f(x) IS 2 on 0, 4] f(I) is on (0, 4) f(0) - f(4) = Then by Rolle's theorem, there exists a c such that f' (c) - 0. Find the value c. 2
