Plotting a cubic function using x, y, and z points.
Exactly what would a cubic function look like, if z points were used as well (ie, if the graph was 3, not 2 dimensional).
I see.
What?
That you don't.

Depends on what, exactly, the function is. Plenty of 3D graphing programs out there. Pick one, pick an equation, and see for yourself.

You mean something like z = x^{3} + y^{3} or what?

If you're talking about a 2 variable function z = f(x, y), then a cubic function would produce some sort of surface depending on the form of the equation.
In general, an nvariable function creates a ndimensional surface.

That isn't necessarily true. Consider for example space curves. However, functions describing ndimensional surfaces can generally be parametrized in n and no fewer than n variables.
