2 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.

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