The zeros would be -1, 2, and 5 right?

Then I would take the derivative of that and get that f'(x)=3x^2-12x+3.

Then what do I do from here? I vaguely remember something about finding critical points using intervals, but I don't really remember how to do that. Do I maybe need the second derivative?

f is increasing where f' > 0

f is concave up where f'' > 0

f has an inflection point where f'' = 0
