Identify the inflection points and local maxima and minima of the function graphed to the right. Identify the open intervals on which the function is differentiable and is concave up and concave down. Find the inflection point(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The point(s) is/are (Type an ordered pair. Use a comma to separate answers as needed.) OB. There are no inflection points. Find each local maximum. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. OA. There is one local maximum value of at x = OB. There are two local maxima. In increasing order of x-value, the values are at x = and at x = OC. There are no local maxima. Find each local minimum. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A. There is one local minimum value of at x = B. There are two local minima. In increasing order of x-value, the values are at x = and at x = OC. There are no local minima. Find the open interval(s) on which the function is differentiable and concave up. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The interval(s) is/are (Use a comma to separate answers as needed. Type your answer in interval notation.) OB. The function is never concave up. Find the open interval(s) on which the function is differentiable and concave down. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The interval(s) is/are (Use comma to separate answers as needed. Type your answer in interval notation.) OB. The function is never concave down. -733 y = 2x + sin 4x, 5x5 f + 3 w | 21 ✪
