Hi can someone help me out with this question:

f (x) = 12x^3 - 5x^2 - 11x +6

I have to do the following, and am allowed to use a graphing calculator:

x - intercepts
degree of polynomial
y-int
Domain
Range
Intervals of increase/decrease
Local Minima
Local Maxima
End Behavior


I've done a few of those but for some of them I'm really stuck... can someone spare a few minutes to help me out?

Thanks
