Question

Determine whether each relation is a function. Find the domain and range.

{(10, 2), ( −10,2), (6, 4), (5, 3), ( −6,7)

Answer 1

This relation is not a function because both (10, 2) and (-10, 2) have the same x-coordinate but different y-coordinates, meaning that there is more than one output for the input of 2.

The domain of this relation is {-10, -6, 5, 6, 10}.

The range of this relation is {2, 3, 4, 7}.
