Af (x) Use the given graph of f'(x) to find the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema. Sketch a possible graph of y = f(x). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The function f(x) is increasing on (Type your answer using interval notation. Use a comma to separate answers as needed.) O B. There is no solution. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The function f(x) is decreasing on. (Type your answer using interval notation. Use a comma to separate answers as needed.) O B. There is no solution. Regarding the local extrema of the function f(x), which statement is true? O A. The function has a local maximum at x - - 1 and a local minimimum at x = 7. O B. The function has a local minimum at x - - 1 and a local maximum at x = 7. O C. The function has no local extrema. Choose a correct possible graph of y = f(x) below. O A. O B. O c. Ay
