Question

Consider f(x) = - 8 sin² x - 16 cos x on [0, 2π].
Determine the intervals on which f is concave down.
f is concave down on:
f is concave down nowhere.
Determine the intervals on which f is concave up.
f is concave up on:
f is concave up nowhere.
Determine the value and location of any inflection point of f. Enter the solution in (x, f(x)) form. If multiple solutions exist, use a comma-separated list to enter the solutions.
f has an inflection point at:
f has no inflection point.
