Identify the mapping diagram that represents the relation and determine whether the relation is a function. {(–2, –4), (–1, –4), (3, –4), (6, –4)}
The mapping diagram that represents the relation is:
-2: -4
-1: -4
3: -4
6: -4
The relation is a function because each input value (x-coordinate) corresponds to one and only one output value (y-coordinate).
