· The equilibrium solutions are to this differential equation are y = − 2 y = − 2, y = 2 y = 2, and y = − 1 y = − 1. Below is the sketch of the integral curves. From this it is clear (hopefully) that y = 2 y = 2 is an unstable equilibrium solution and y = − 2 y = − 2 is an asymptotically stable equilibrium solution.
