A relation exists between two sets of numbers if we can find a ​ that maps members of the first set (​ (a)   ​ ) onto members of the second set (​codomain). The ​ (b)   must hold for all possible pairs that are connected. So that when we select a value of x, also called an ​​ (c)   , and apply the rule of the relation, we obtain the ​ (d)   ​ , also called the ​​ We can also refer to the​ y value ​ as the ​ of the ​ ​of the ​output. We can also refer to the y value as the ​ (e)   of the x value ​.
