(1 point) Considerthe function z : 277g + 73:6 1y. 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 m-coordinate is f , ) Classication: (local minimum, local maximum, saddle point, cannot be determined) The critical point with the next smallest m-coordinate is ( , ) Classication: (local minimum, local maximum, saddle point, cannot be determined]
