Decide with justification whether the value is positive, negative or zero

Problem 2. Below are contour diagrams for two functions f (on the left} and g [on the right}, both dened on the region R consisting of all points {my} such that 3 g m :2 3 and 3 g y :1 3. The contours of both functions are circular arcs centered at (3,3); the contours shown in each picture are equally farther apart in heights and in the mgrplane. The contours of both functions are identical, except that the two functions have different values on these oontous's. Answer the following questions (of course, explain your reasoning). z = ag) 2 = g[a',y} L L 3 3 3 3 an {1)} Decide, with justzmtion, Whether the value of ff 1' f (2:, 33) (14 is positive, negative, or zero.
