{(-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.
A function can then be defined as a set of ordered pairs: Example: {(2,4), (3,5), (7,3)} is a function that says. 2 is related to 4, 3 is related to 5 and 7 is related 3. Also, notice that: 1  the domain is {2,3,7} (the input values).
