A relation is considered a function if every input, otherwise known as a domain value, is matched with one distinct output, also referred to as a range value. In essence, this indicates that in the relation, no two different ordered pairs share the same first element. When visualized graphically, a relation can be identified as a function if it successfully meets the criteria of the vertical line test.
