Parametric modelling

[wildfire634]

Does autograph have parametric modelling functions? Because I need to graph y= 2.5t[sup]3[/sup] -15t[sup]2[/sup]. This is supposed to represent the position of an elevator (y) through time (t). I would need autograph to show the elevator\'s path through time, its velocity and its acceleration. But is this possible?  ??? If it is message me   and help an Autograph-newbie out.
