I elaborated on Brent's excellent suggestion for a post to k12.ed.math
(which you can check via http://www.mathforum.com/epigone/k12.ed.math/ ).
The Poly objects are in play:
>>> f = Poly([2,3,4])
>>> f
Polynomial: 2*x**2 + 3*x + 4
>>> f(10)
234
>>> f.degree
2
>>> f.deriv()
Polynomial: 4*x + 3
>>> df = f.deriv()
>>> df(10)
43
>>> g = Poly([-1,0,0,2])
>>> g
Polynomial: -1*x**3 + 2
>>> g(-1)
3
>>> dg = g.deriv()
>>> dg
Polynomial: -3*x**2
>>> dg(-1)
-3
