Consider the function [math]. Find and classify all critical points of the function. If there are more blanks than critical points, leave the remaining entries blank. The critical point with the smallest [math]-coordinate is
( , ) Classification: (local minimum, local maximum, saddle point, cannot be determined)

The critical point with the next smallest [math]-coordinate is
( , ) Classification: (local minimum, local maximum, saddle point, cannot be determined)

The critical point with the next smallest [math]-coordinate is
( , ) Classification: (local minimum, local maximum, saddle point, cannot be determined)
