3-D graphing software?

[Dotan Cohen]

In an advanced Calculus course, we are dealing with functions with 2
(and more) variables. Is there any 3-D graphing software for Fedora
available? Something like Kalgebra, but with a bit more functions such
as multiple functions graphed at the same time, asymptote min max and
other significant points, zoom into 3-D graph, graph of derivative and
integral, etc. Thanks in advance for any suggestions.
