Use the graph to find the point(s) of inflection of f.
(Give your answer in the form of a comma-separated list of values. Express numbers in exact form. Use symbolic notation and
fractions where needed. Enter DNE if the function has no inflection points.)
x =
Use the graph to determine the interval(s) on which the function f is concave down.
(Give your answer as an 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. Use
decimal notation. Give your numbers to three decimal places.)
