Identify the mapping diagram that represents the relation and determine whether the relation is a function {(-1,-9),(0,-9),(4,-9),(5,-9)}
The mapping diagram that represents the relation {(-1,-9),(0,-9),(4,-9),(5,-9)} is as follows:
-1 -> -9
0 -> -9
4 -> -9
5 -> -9
From the mapping diagram, we can see that each input value (x-value) is associated with one and only one output value (y-value). Therefore, the relation is a function.
