Which of the following statements is TRUE? a. If f(x) and g(x) are differentiable functions defined on the closed interval [a, b], and f(x) attains its global maximum at x = c and g(x) d, then the function f(x) · g(x) attains its global maximum at x = attains its global maximum on [a, b] at x = c•d. O b. The critical points of f' (x) are same as the critical points of f(x) The global maximum value of a differentiable function f(x) on a closed interval [a, b] must occur at a critical value or an endpoint. C. d. All of the statements are false. e. Every local maximum is a global maximum
