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. y = f"(x) 8 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.
