Which of the following best describes the ordered pairs listed below?

(-2, 0), (0, -4), (6, -16), (8, -20)

both a relation and a function
neither a relation nor a function
relation only
function only



Answer :

it is a function. This is because the x's don't repeat.

This indeed is both a relation and a function because it is a set of ordered pairs and the x-axis does not repeat itself.
