identify the mapping diagram that represents the relation and determine whether the relation is a function.
{(-2, -5), (-1, -3), (-2, 6), (5, 7)}
The mapping diagram that represents the relation {(-2, -5), (-1, -3), (-2, 6), (5, 7)} would look like this:
-2 → -5
-1 → -3
-2 → 6
5 → 7
In this mapping diagram, we can see that the input value -2 is associated with two different output values: -5 and 6. Therefore, the relation is not a function.
