1. A function f[r,y} is given to you as a contour diagram on the region R = [21 2] x [2, 2]: -2 -1.5 -1 -0.5 0 0.5 1 1.5 2 Note that the contour lines are given for fvalues that are multiples of 3; so there is ambiguity about the value of the function between the contour lines. It is clear though from the diagram that on R, 0
