*f(x)= x^2 + b x + c
*

When *b=0*, this is the famous quadratic mapping of the real interval.
(See R. Devaney, *An Introduction to Chaotic Dynamical Systems*,
Benjamin-Cummings, 1986.

The set of points for which *f(x)-x=0* are the fixed points
for this mapping. The set of points for which
*f(x)-x = f'(x)-1 = 0* are called points of saddle-node bifurcation.

Since this model has a one-dimensional domain, one or more of the parameters must be permuted into the domain before attempting to trace level sets.
