Iterated function
From Wiki @ Karl Jones dot com
In mathematics, an iterated function is a function X → X (that is, a function from some set X to itself) which is obtained by composing another function f : X → X with itself a certain number of times.
Description
The process of repeatedly applying the same function is called iteration.
In this process, starting from some initial number, the result of applying a given function is fed again in the function as input, and this process is repeated.
Iterated functions are objects of study in computer science, fractals, dynamical systems, mathematics and renormalization group physics.
