This 2-variable function has exactly TW0 critical points: 8 f (x, y) = xy 3 One of them is (0, 0) and we don't care about that one. (a) Find the other critical point. SHOW ALL ALGEBRA! (b) LOCAL MAX, LOCAL MIN, or SADDLE POINT. SHOW ALL ALGEBRA! Use the Second Partials Test and classify the critical point from part (a).
