Be sure to include information about domain, intercepts, asymptotes, relative extreme poins and inflection ploints. also include information about concavity and about where the function is increasing and where it is decreasing. than use the information to sketch a graph of each functions must show work.

1.f(x)-x^3+5x^2-8x

2.F(x)=x-2/x^3

3. G(x)=(x^2+1)e^x
