Select the correct choice below and fill in the answer box(es) to complete your choice (Simplify your answer. Type your answer in interval notation. Use a comma to separate answers as needed. Use ascending order.) O A. The function is concave up on and concave down on OB. The function is concave down on and the function is never concave up. OC. The function is concave up on and the function is never concave down. Locate any inflection points off. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. An inflection point occurs at x = (Use a comma to separate answers as needed.) OB. There are no inflection points for f.
