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 would be:
-1 -> -9
0 -> -9
4 -> -9
5 -> -9
To determine if this relation is a function, we need to check if each input value (x-value) is associated with only one output value (y-value).
In this case, every input value (x) is associated with the same output value (-9). So, for any x-value, there is only one y-value.
Therefore, the relation is a function.
