Graph Rational functions

[woooo]

I am stuck on this problem and i need to finish this by today so that i can submit this by tom..

Sketch the graph of function Q(x) = x^3 - 1 / x^3 + 1. Determine the prime
factorization of Q(x) and graph the polynomial function.

Thanks !

What part is troubling you? You should know the "Difference of Cubes" factorization. It is a standard form to be memorized.

x^3 - y^3 = (x-y)(what?)

x^3 + y^3 = (x+y)(what?)
