(1 point) Consider the function f(x, y) = et cos(7y). Find and classify all critical points of the function. If there are more blanks than critical points, leave the remaining entries blank. fa= faz = fry = The critical point with the smallest x-coordinate is Classification: (local minimum, local maximum, saddle point, cannot be determined) The critical point with the next smallest x-coordinate is * ) Classification: (local minimum, local maximum, saddle point, cannot be determined) The critical point with the next smallest x-coordinate is Classification: (local minimum, local maximum, saddle point, cannot be determined)
