Question

Identify the mapping diagram that represents the relation and determine whether the relation is a function.



{(-7, -5), (-4, 3), (-7, 2), (8, 4)}

Answer 1

Domain: {−7, −4, 8}
Range: {−5, 3, 2, 4}

Mapping diagram (arrows):
- −7 → −5
- −7 → 2
- −4 → 3
- 8 → 4

This is not a function, because the input −7 is paired with two different outputs (−5 and 2).
