a. Bifurcation of Z with respect to v. Red and blue branches are the unstable and stable solutions. At v = 24, there are three distinct solutions for Z (stable, unstable, stable). b. Bifurcation of Y with respect to v. Red and blue branches are the unstable and stable solutions. At v = 24, there are two repeated stable solutions for Y at 18 (shown by black circle) and one unstable solution at 19
