Thanks to Bob and Dan for helping me get this far. Again, I've exhausted
my Mathematica knowledge along with anything I can find in the Help
files.  I now need to take the function they found for me and graph it
in 3D over a restricted domain. Here's the problem:

Graph the function

f(x,y) = -64*x + 320*(x^2) - 512*(x^3) + 256*(x^4) + 20*y - 64*x*y +
64*(x^2)*y - 4*(y^2) 

over the domain:

y <= 4*x*(1-x)
y >= 4*x*(1 - 2x)
y >= 4*(x - 1)*(1 - 2x) 

Thanks for any help.

Dick
