Answer:

See a solution explanation below:

Explanation:

In the set of ordered pairs {(-2, 0), (0, 6), (2, 12), (4, 18)}, the domain is the set of the first number in every pair (those are the x-coordinates):

{-10, -5, 0, 5, 10}.

The range is the set of the second number of all the pairs (those are the y-coordinates):

{-10, -5, 0, 5, 10}.
