All functions are relations but not all relations are functions. Dependent and Independent Variables The x-number is called the independent variable, and the y-number is called the dependent variable because its value depends on the x-value chosen.

All functions, then, can be considered as relations also. ... We have seen that certain common relations such as "=", and congruence (which we will deal with in the next section) obey some of these rules above. The relations we will deal with are very important in discrete mathematics, and are known as equivalence relations.
