Determine the intervals on which the graph of y = f(x) is concave up or concave down, and find the points of inflection. f(x) = (x² - 15) ex Provide intervals in the form (*, *). Use the symbol for infinity, U for combining intervals, and an appropriate type of parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter Ø if the interval is empty. Provide points of inflection as a comma-separated list of (x, y) ordered pairs. If the function does not have any inflection points, enter DNE. Use exact values for all responses. f is concave up when x E f is concave down when x E points of inflection:
