I think the best start point is to use Plot3D. For example,
Plot3D[x^2+y^2,{x,0,3},{y,0,3}] will plot the paraboloid z=x^2+y^2.
As you can see if you have a surface z=f(x,y), you can plot it using
Plot3D[f(x,y),{x,a,b},{y,c,d}].
Also you can plot 3D surfaces using ParametricPlot3D. The prior
paraboloid can be plotted too using:
ParametricPlot3D[{u,v,u^2+v^2},{u,0,3},{v,0,3}]
Moreover, this functions have several options (draw axes or not, dra
box or not, so on). If you need some more information I can help you!
Wishes!
