Problem 5. (1 point) Here is a contour plot of the function f(z, y) = 4 +23 + y- 3xy. (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 intuition. The critical point (1,1) is a | ??? (choose one from the list). he second critical point is at the point and it is a ??? te: You can earn partial credit on this
