A relation is any set of points which connect two variables A relation is any set of points which connect two variables. A relation is often expressed in the form of an equation connecting the variables x and y. In this case the relation is a set of points (x,y) in the Cartesian plane.

A function, sometimes called a mapping, is a relation in which no two different ordered pairs have the same x –coordinate.

The domain of a relation is the set of x values The range of a relation is the set of y values
