where f _{x,n} is an attractor For an infinite recurrent parabola
y = ax (1x) we can compute the possible function values, as function of the parameter a.
The resulting pattern is a bifurcation ^{1)},
a forklike ramification. The shown bifurcation belongs to the above mentioned parabola.
For other polynomials sometimes symmetry around the xaxis be reached.
The generalization for the bifurcation to the complex numbers is the Mandelbrot set.
