A relation between two sets X and Y is a set of ordered pairs, each of the form (x, y), where x is a member of X and y is a member of Y. A function from X to Y is a relation between X and Y that has the property that any two ordered pairs with the same xvalue also have the same yvalue. The variable x is the independent variable, and the variable y is the dependent variable.
