Retest Question #1: Identify the mapping diagram that represents the relation and determine whether the relation is a function. {(-7, -5), (-4, 3), (-7, 2), (8, 4)}
The mapping diagram that represents the relation is:
-7 -> -5
-4 -> 3
-7 -> 2
8 -> 4
We can see that -7 is mapped to both -5 and 2, which means that there are multiple outputs for the same input. Therefore, this relation is not a function.
