How do I limit x and y ranges in Maple's plot3d?

[MAins]

How do I use maple to plot a corresponding surface?

I have f(x,y)=(2x+y etc.
I need to plot for x greater than or equal to 5, y less than or equal to 2.

I'm guessing I probably need to do plot3d, but how do I write the limits of x and y? when I write x=5..infinity it doesn't work. Any suggestions?

You will have to choose some largest value for x and y yourself.
