Question: Consider f(x) = - 8 sin x - 16 cos x on [0, 2?].Determine the intervals on which f is concave down.f is concave down

Consider f(x) = - 8 sin² x - 16 cos x

Consider f(x) = - 8 sin² x - 16 cos x on [0, 2?].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.
