Question

The domain and the range of the relation, and tell whether the relation is a function.

{(13,5), (26,-2), (36,5), (13,1), (46,1)}

Answer 1

The domain of the relation is {13, 26, 36, 46}, and the range is {5, -2, 1}. However, this relation is not a function because it has multiple outputs (5 and 1) for the input value 13. In a function, each input can only have one corresponding output.
