In mathematics, a relation is a connection or association between elements of two sets. It pairs elements from one set (called the domain) with elements of another set (called the codomain). For example, in a relation \( R \) from set \( A \) to set \( B \), each element in \( A \) can be paired with one or more elements in \( B \).
A function is a specific type of relation where each element in the domain is associated with exactly one element in the codomain. In other words, for a relation to be a function, no two ordered pairs can have the same first element with different second elements. Functions are commonly denoted as \( f(x) \), indicating that each input \( x \) yields a single, unique output.
