In mathematics, some functions or groups of functions are important enough to deserve their own names. This is a listing of articles which explain some of these functions in more detail. There …

In math, we like to keep things easy, so that's pretty much how we're going to define a function. A function is an object f that takes in an input and produces exactly one output. (This is not a …

Apr 7, 2025 · In mathematics, a function is a relationship or rule that assigns each input (often called the domain) to exactly one output (often called the co-domain). This section introduces …

Topics include formal logic notation, proof methods; induction, well-ordering; sets, relations; elementary graph theory; integer congruences; asymptotic notation and growth of functions; …

May 7, 2024 · Functions are mathematical constructs that model relationships between inputs and outputs. In math, a function is like a machine that takes an input (usually a number) and …

5 days ago · Given two sets X X and Y Y, a function from X X to Y Y maps each value in X X to exactly one value in Y Y. A function can be thought of as a "machine" that provides exactly …

A function assigns an element of one set, called the domain, to an element of another set, called the codomain. The notation \[\nonumber f: A \rightarrow B\] indicates that \(f\) is a function with …

What is a Function? A function relates an input to an output. It is like a machine that has an input and an output. And the output is related somehow to the input. " f (x) = ... " is the classic way …

This page explains essential concepts of mathematical mapping, particularly focusing on functions, including definitions of key terms like function, surjective, injective, bijection, and …
