{(-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.
Repetition of the elements are immaterial. The number of elements in a set '$A$' is denoted as $|A|$, is called the cardinality of the set, a set with no elements. Relationship between sets can be represented by venn diagrams. A relation describes certain properties of things and is a set of ordered pairs. It is a subset of ordered pairs drawn from the set of all possible ordered pairs. $R$ is a relation if. $R \subseteq {(x, y) |x\ \epsilon \ X,y\ \epsilon Y}$. Here Domain is $X$ and Codomain is $Y$.
