{(-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.
If we impose the following rule on a relation, it becomes a function. Function: A function is a set of ordered pairs in which each x-element has only ONE y-element associated with it. Function: A function is a set of ordered pairs in which each x-element has only ONE y-element associated with it.elation: A relation is simply a set of ordered pairs. The first elements in the ordered pairs (the x-values), form the domain. The second elements in the ordered pairs (the y-values), form the range.
