(1 point) Here is a contour plot of the function f(z, y) - 4 + 23 + 1 - say (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 your intuition. The critical point (1,1) is a ??? (choose one from the list) The second critical point is at the point , and it is a ??? ???
