{(-1, 3), (-2, 5), (-3, 3), (-5, -3)}. To show that the four ordered pairs belong together in a set, we list them with commas in between each and brackets around the group. As with other methods of representing relations, we can check the characteristics of a set of ordered pairs to determine if it is a function.he next table does not represent a function. The x column has two values that are 3, and they correspond to two different values for y. Remember, when a single input can produce multiple outputs, the relation is not a function.
Two ordered pairs and are equal if and only if a = c and b = d. For example, if the ordered pair is equal to, then a = 1, and b = 2. is not equal to the ordered pair. Definition (binary relation): A binary relation from a set A to a set B is a set of ordered pairs where a is an element of A and b is an element of B.When an ordered pair is in a relation R, we write a R b, or R.It means that element a is related to element b in relation R.When A = B, we call a relation from A to B a (binary) relation on A. Definition (Cartesian product):hen an ordered pair is in a relation R, we write a R b, or R. It means that element a is related to element b in relation R. When A = B, we call a relation from A to B a (binary) relation on A. Definition (Cartesian product):
