May 27, 2017

#### Answer:

See a solution explanation below:

#### Explanation:

In the set of ordered pairs {(7, 4), (7, -6), (7, -4)}, the domain is the set of the first number in every pair (those are the x-coordinates):

{7}.

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

{4, -6, -4}.
