Answer:

Domain: #{-7, 5}#

Range: #{0, 3, 8}#

Explanation:

The domain is also known as the #x#-values and the range is the #y#-values.

Since we know that a coordinate is written in the form #(x, y)#, all the #x#-values are:
#{5, -7, -7, 5}#

However, when we write a domain, we typically put the values from least to greatest and do not repeat numbers. Therefore, the domain is:
#{-7, 5}#

All the #y#-values are:
#{0, 8, 3, 3}#

Again put them in least to greatest and do not repeat numbers:
#{0, 3, 8}#

Hope this helps!
