Answer
Domain: {-2, -1, 0, 5}, Range: {2, 6, 7}, Yes
Work Step by Step
The domain is the set of all first components of the ordered pairs, or {-2, -1, 0, 5}. The range is the set of all second components of the ordered pairs, or {-2, 6, 7}. This relation is a function because each specific value of the domain corresponds to only one value of the range.
