Problem. 2 : Use the level curves in the figure to predict the location of the critical points of f(x, y) = 4 + x' + y' + 3ry and whether f has a saddle point or a local maximum or minimum at each critical point. (Order your answers by their ordered pairs, from smallest to largest x.) Then use the Second Derivatives Test to confirm your predictions. 2 . 253 35 25 . P(x, y) with smaller x-value = -1 V - 1 V P is a saddle point local minimum local maximum Correct . Q(x, y) with larger x-value = 0 0 Q is a saddle point local minimum local maximum Correct
