![X =
Determine the interval on which f is concave up.
(Use symbolic notation and fractions where needed. Give your answer as interval in the form (*, *). Use the symbol o for
infinity, U for combining intervals, and an appropriate type of parenthesis "(", ")", "[", "]" depending on whether the interval is
open or closed. Enter Ø if the interval is empty.)
x E
Determine the interval on which f is concave down.
