At what level of Algebra do you want to graph this? You should factor the polynomial and you have something easier to analyze.
f(x)=x(x^2-2x-3)
highlight%28f%28x%29=x%28x%2B1%29%28x-3%29%29

Roots at -1, 0, and 3. At x<-1, f is increasing. At x>3, f is increasing. Between -1 and 0, f is positive. Between 0 and 3, f is negative.
