(4 pts; Review from MFE 1) Let f ( x, y ) = x 2 + 2 xy 2 + 2 y 2 . Find all critical points of f , and classify each critical point as a local min, local max, or saddle point. Does f have a global maximum value? Briefly justify. 2. (4 pts) Use Lagrange multipliers to find the maximum and minimum values of f subject to the given constraint if such values exist. If there is no minimum, justify why. If there is no maximum, justify why. f ( x, y ) = x 2 + y , x 2 - y 2 = 1 3. (7 points) Use Lagrange multipliers to find the maximum and minimum values of f subject to the given constraint if such values exist. If there is no minimum, justify why. If there is no maximum, justify why. f ( x, y ) = x 2 y + 3 y 2 - y, x 2 + y 2 10 .
