- In mathematics, a function is a relation that assigns to each element of a set X exactly one element of a set Y12345. Key points about functions:
- The set X is called the domain of the function.
- The set Y is called the codomain or range of the function.
- A function relates inputs (domain) to outputs (codomain).
- Each input is related to exactly one output.
