In mathematics, the composition operator takes two functions, and , and returns a new function . Thus, the function g is applied after applying f to x. Reverse composition, sometimes denoted , applies the operation in the opposite order, applying first and second.
A composite function is a function created when one function is used as the input value for another function. Essentially, the output of the inner function (the function used as the input value) becomes the input of the outer function (the resulting value).

"Function Composition" is applying one function to the results of another. (g º f)(x) = g(f(x)), first apply f(), then apply g() We must also respect the domain of the first function; Some functions can be de-composed into two (or more) simpler functions.
The function produced by combining two functions is a composite function. See Example and Example. The order of function composition must be considered when interpreting the meaning of composite functions.
Create a new function by composition of functions. Evaluate composite functions. Find the domain of a composite function. Decompose a composite function into its component functions.
What is the Composition of Functions? The composition of functions f (x) and g (x) where g (x) is acting first is represented by f (g (x)) or (f ∘ g) (x). It combines two or more functions to result in another function.
