In mathematics, functions are relationships that assign each input exactly one output, often described as mappings between sets. They can be represented by formulas, graphs, tables, or verbal descriptions. In computer science, functions are reusable blocks of code that perform specific tasks and can return values. They help structure programs, avoid repetition, and improve readability. In general English, the term can also refer to roles or purposes that something serves within a system. Despite these different contexts, the core idea is a defined operation that links an input to a particular result or fulfills a specific role.
