Answer Question

Question 3 5 pts The second derivative f"(x) of a function is given. In each case, use this information to determine where the graph of f (x) is concave upward and concave downward and find all values of x for which an inflection point occurs. [ You are not required to find f (x) or the y coordinates of the inflection points.] f" ( x) =x(x- 9)(x- 4) O Concave upward for x 9; concave downward for 4 9; concave downward for x 9; inflection points at x = 0, 4, 9 O Concave upward for 4 9; inflection points at x = 4, 9
