Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have the function [tex] 0.1x^3 - 3x[/tex] and I would like to find its local maxima and minima within the domain of [-10,10]. The problem is I don't think we've been taught a way yet; I'm currently in Calculus I and just before derivatives. Is there a way within my current knowledge to find the fraction representing the max and min of this function within the above domain?
