The Verhulst process

${\displaystyle v_{k}:x\mapsto kx(1-x)}$

is equivalent to the process

${\displaystyle f_{c}:z\mapsto z^{2}+c}$

by means of a linear transformation ${\displaystyle \Phi }$, i.e.

${\displaystyle \Phi ^{-1}\circ v_{k}\circ \Phi =f_{c}}$

Just let

${\displaystyle \Phi :x\mapsto {\tfrac {1}{2}}-{\tfrac {1}{k}}x}$

and observe that the Parameters ${\displaystyle c}$ and ${\displaystyle k}$ are connected via

${\displaystyle 1-4c\,=\,(k-1)^{2}}$
