The relation is a function because each input (x-value) corresponds to exactly one output (y-value). The domain is {-4, -3, 0, 3, 5} and the range is {-5, 4, 11, 20}. Choice B matches this answer. The relation {(-4, 11), (-3, 4), (0, -5), (3, 4), (5, 20)} is a function because each input (x-value) corresponds to exactly one output (y-value).

Domain: {-4, -3, 0, 3, 5}

Range: {11, 4, -5, 20}
