Answer:

Domain: {0, 2, 1.4, -3.6}
Range: {-1.1, -3, 2, 8}
Relation a function? yes

Explanation:

The domain is the set of all given x-values. The x-coordinate is the first value listed in an ordered pair.

The range is the set of all given y-values. The y-coordinate is the last value listed in an ordered pair

The relation is a function because each x-value maps to exactly one unique y-value.
