Determine the intervals on which the given function is concave up or concave down and find the points of inflection.
f(x) = (x – 14)(1 – x³)
(Use symbolic notation and fractions where needed. Give your answer as a comma separated list of points in the form in the
form (*, *). Enter DNE if there are no points of inflection.)
points of inflection: (x, y) =
(0,–14),(7,2394)
(Use symbolic notation and fractions where needed. Give your answers as intervals in the form (*, *). Use the symbol o 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.)
