PLEASE HELP ME ANSWER THIS QUESTION

Use the graph of f' and f" to find the critical points and inflection points of f, the intervals on which f is increasing and decreasing, and the intervals of concavity. Then, graph f assuming f(0) = 0. Find the critical points. The critical points are x = .(Use a comma to separate answers as needed.) Find the inflection points. The inflection points occur at x = . (Use a comma to separate answers as needed.) Find the intervals on which f is increasing and decreasing. f is increasing on (Type your answer in interval notation. Use a comma to separate answers as needed.) f is decreasing on (Type your answer in interval notation. Use a comma to separate answers as needed.) Find the intervals of concavity. f is concave down on (Type your answer in interval notation. Use a comma to separate answers as needed.) f is concave up on (Type your answer in interval notation. Use a comma to separate answers as needed.) Graph f assuming f(0) = 0. Choose the correct graph below
