The catastrophe locus in the space of parameters a, b, c for the most general perturbation of f(x) = x^{5}. The locus separates perturbations with no minimum (greensided region), perturbations with one minumum (bluesided region) and perturbations with two minima (pinksided region). 
The red line is a onedimensional section of parameter space which, read going upwards, has a process change from one minimum to two minima, then back to one minimum which disappears. The corresponding verb class is suicide: the subject emits an instrument which then kills it: "The bird lays an egg, swallows it, and dies."
