 Solution

At zero, $F^{\prime }(0)=-(1+\mu )$, so it is stable for $-2<\mu <0$, loses stability through multiplier $+1$ at $-2$ and $-1$ at $0$. Nonzero fixed points areborn in a saddle-node at $\mu =-2-q^2/(4p)$. Their stability follows from $F^{\prime }(x_{\ast })=3+\mu +p{x}_{\ast }^2$; $|F^{\prime }|<1$ marks solid branches. Thus the three bifurcations are the saddle-node, the exchange at $-2$, and the flip at $0$.
