Question

f is defined and continuous on x [-5, 4] The only critical points of f are x = -3 and x = 1 f'(-4) = 5, f'(0) = 2, f'(2) = -1 Write the letter of the correct answer choice in the space provided and also circle the letter of the correct answer choice. No justification required. Which of the following must be true: f has a local maximum at x = -5 f has a local minimum at x = -5 f has neither a local maximum or minimum at x = -5 Impossible to determine whether or not f has a local extrema at x = -5. Which of the following must be true: f has a local maximum at x =-3 f has a local minimum at x = -3 f has neither a local maximum or minimum at x = -3 Impossible to determine whether or not f has a local extrema at x = -3 Which of the following must be true: f has a local maximum at x = 1 f has a local minimum at x = 1 f has neither a local maximum or minimum at x = 1 Impossible to determine whether or not f has a local extrema at x = 1. Which of the following must be true: f has a local maximum al x = 4 f has a local minimum at x = 4 f has neither a local maximum or minimum at x = 4 Impossible to determine whether or not f has a local extrema at x = 4.
