Match the functions with the graphs labeled A - G. As always, you may click on the thumbnail image to produce a larger image in a new window (sometimes exactly on top of the old one). Just take your time; process of elimination will help with ones that are not obvious. 1. f(x, y)=sin(y) 2. f(x, y) = 1/(1 + x + y) 3. f(x, y) = 3x - y 4. f(x, y) = sin(x) sin(y)e-x-2 5. f(x, y) = (x - 12)2 6. f(x, y) = cos(x + y)/(1 + x + y) 7. f(x, y) = (x - y)
