Determine whether each relation is a function. Find the domain and range. Show your work
{(10, 2), ( −10,2), (6, 4), (5, 3), ( −6,7)}
This relation is a function because each input value (x-coordinate) is associated with exactly one output value (y-coordinate).
The domain of the relation is {-10, -6, 5, 6, 10}, which is the set of all the x-coordinates.
The range of the relation is {2, 3, 4, 7}, which is the set of all the y-coordinates.
