About this document
Understanding Function Composition by Mark Anthony Dimen is a document available to read on EtoBox.
The document defines composition of functions f and g as f ◦ g(x) = f(g(x)). It provides examples of finding (f ◦ g) and (g ◦ f) for various functions f and g. It also explains how to write functions as compositions of simpler inner and outer functions, such as writing (x2 + 2)6 as f(g(x)) where g(x) = x2 + 2 and f(x) = x6. Finally, it discusses the identity function id(x) = x and how id serves as the identity for function composition.
