Here is a contour plot of the function f a 4 3y Click the image to enlarge it By looking at the contour plot characterize the two critical points of the function You should be able to do this analysis without computing derivatives but you may want to compute them to corroborate intuition The critical point 1 1 is a local The second critical point is at the point choose one from the list and it is a saddle point 0
