PLEASE HELP ME ANSWER THIS QUESTION

Complete parts a through c for the given function. f(x)= - 4x -x+5; [-3,3] a. Locate the critical point(s) of f. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The critical point(s) Is(are) at x = (Simplify your answer. Use a comma to separate answers as needed.) O B. The function does not have a critical point. b. Use the First Derivative Test to locate the local maximum and minimum values. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Simplify your answer. Use a comma to separate answers as needed.) O A. The local maximum/maxima is/are at x = O B. The local minimum/minima is/are at x = and the local maximum/maxima is/are at x = O C. The local minimum/minima is/are at x = D. There is no local minimum and there is no local maximum. c. Identify the absolute maximum and minimum values of the function on the given interval (when they exist). Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. (Simplify your answer. Use a comma to separate answers as needed.) O A. The absolute maximum is at x = but there is no absolute minimum. B. The absolute minimum is at x = , but there is no absolute maximum. O C. The absolute maximum is at X = and the absolute minimum is at x = O D. The function has no absolute extrema
