a Find the critical point of f x y 2x y z 4y x y 6x b Find the discriminant D x y for the function D x y 0 what is the value of the discriminant at the critical point D 48 0 14 0 8 14 0 What does this tell us about the critical point The discriminant doesn t tell us anything c Sketch contours near the critical point to determine or confirm whether it is a local maximum a local minimum a saddle point or none of th The critical point is a saddle point
