Definitions:

Function

A scheme relating a bundle of inputs with a spectrum of viable outputs, under the condition that each input is matched with one output exclusively.

Composition

In mathematics, composition refers to the application of one function to the results of another, denoted as \(f(g(x))\), where \(g\) is applied first and then \(f\).

Function

A connection framework between a pack of inputs and a slew of endorsed outputs, ensuring each input leads to a distinct output.

Composition

In mathematics, the operation of applying one function to the results of another, denoted as \((f \circ g)(x) = f(g(x))\).
