The net force acting on an object constrained to the x axis is given by Fx(x) = x3 - 4x. (the force is in newtons and xin meters). Locate the positions of unstable and stable equilibrium. Show that each position is stable or unstable by calculating the force one millimeter on either side of the locations.
