Answer:
Relations are defined as sets of ordered pairs. Ordered pairs are values that go together. This means that if one value is used, the other must be present.
Here is an example: If (4,8) is an ordered pair, then it implies that if the first element is 4 the other is designated as 8. A relation may have more than one output.
On the other hand, a function is a relation where one x-element (or the output) has one Y-element (or the input associated with it).
In ordered pairs, a relation becomes a function if the x-value is not repeated.
If the values were to be plotted on a graph, a relation could become a function if no vertical lines intersect at any point in the graph.
Here are real-life examples of relations and functions.
