ANSWER
Domain: {-4, -3, 1}
Range: {1, 3, 4}
EXPLANATION
The domain is the set of all x-values of the relation and the range is the set of all y-values.
In the second relation we have a set of points. We get the domain by selecting the x-coordinates of each point and the range by selecting the y-coordinates:
If the values repeat we just write them once.
The x-coordinates are:
[tex]-4,-4,-3,1[/tex]
So the domain is:
[tex]\lbrace-4,-3,1\rbrace[/tex]
The y-coordinates are:
[tex]3,4,1,1[/tex]
So the range is:
[tex]\lbrace1,3,4\rbrace[/tex]
