Definition

A composite function is a function that is formed when one function is applied to the result of another function.

Description

Composite functions are significant in mathematics because they allow the combination of two functions to form a new function. This is denoted as (f∘g)(x) = f(g(x)). Composite functions are widely used in various fields, including computer science for function composition in programming and in calculus for chain rule applications. For example, if f(x) = 2x and g(x) = x + 3, then the composite function 

(f∘g)(x) = f(g(x)) = 2(x + 3) = 2x+6

Understanding composite functions is crucial for solving complex mathematical problems and for the analysis of functions in higher mathematics.
