The Domain: -2, 8, 3, 5 The Range: 5, 6, 12, 6 Relation is not a function.

Work Step by Step

The domain and and range are simply the x and y terms respectively. The Domain is the x-terms and the Range is the y-terms. We decided that this relation is not a function because there are two y terms for 1 x term. The domain value of 8 and 5 both share a range value of 6 so therefore the relation cannot be a function.
