Suppose that the graph shown is the graph of f'(x), the derivative of f(x). Find the open intervals where the original function is concave upward or concave downward. Find any inflection points. Ay f ((* ) O A. The original function has (an) inflection point(s) at x = (Round to the nearest integer as needed. Use a comma to separate answers as needed.) O B. The original function has no inflection points. Find the open intervals where the function f is concave upward. Select the correct choice below and, if X necessary, fill in the answer box to complete your choice. Question Viewer 108 -6 -4 25 2 4 6 8 10 12 14 16 18 20 O A. The original function is concave upward on the interval(s) (Type your answer in interval notation. Use a comma to separate answers as needed.) O B. The original function is never concave upward. Find the open intervals where the function f is concave downward. Select the correct choice below and. if necessary, fill in the answer box to complete your choice. O A. The original function is concave downward on the interval(s) (Type your answer in interval notation. Use a comma to separate answers as needed.) O B. The original function is never concave downward.
