Find critical points from second derivative
WebExpert Answer. Use the first derivative to find all critical points and use the second derivative to find all inflection points. Use a graph to identify each critical point as a local maximum, a local minimum, or neither. f (x) = x4 −4x3 +8 Enter the exact answers in increasing order.
