Consider the function below. f (x) = x (x2 - 4x - 9) Determine whether the Mean Value Theorem can be applied to f on the closed interval [-1, 1]. (Do this on paper. Your instructor may ask you to turn in this work.) If the Mean Value Theorem can be applied, find all values of c in the open interval (-1, 1) such that the following is true. If it cannot be applied, enter NONE. (Give your answer correct to 3 decimal places.) X f(c) = f(b) - f (a) b - a
