Match the functions with the graphs labeled A - G. As always, you may click on the thumbnail image co 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)=11+x2+y22.f(x,y)=3-x2-y23.f(x,y)=(x2-y2)24.f(x,y)=sin(x)sin(y)e-x2-y25.f(x,y)=cosx2+y21+x2+y26.f(x,y)=(x-y)27.f(x,y)=sin(y)
