f(x) = (x\textsuperscript{2}-3) e\textsuperscript{x} 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 ? 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 ? (-?,-2-?15)?(-2+?15,?) Incorrect f is concave down when x ? Incorrect points of inflection: Incorrect
