Identify the mapping diagram that represents the relation and determine with the relation is a function. (-3,2) (-1,5) (-3,9) (2,7)

Answer 1

The mapping diagram that represents the relation is:

-3 -> 2, 9
-1 -> 5
2 -> 7

To determine if the relation is a function, we need to check if each input (x-value) has a unique output (y-value). In this case, the input -3 has two different outputs: 2 and 9. Therefore, the relation is not a function.
