  • A relation is a set of ordered pairs. It can be represented as a table, a graph, or a mapping.

  • The domain of a relation is the set of values given by the first terms of the ordered pairs. The range is the set of values given the second terms.

  • The inverse of a relation R is the relation obtained by interchanging the coordinates in the ordered pairs of R. The domain of the inverse of R is the range of R and the range of the inverse of R is the domain of R.
