Answer:
C. The mapping represents a relation but not a function
Step-by-step explanation:
✔️The relation is a function because every input value (domain) is mapped to exactly one output value (range). So option A is TRUE.
✔️The range consist of 2 and 1 (output values).
Option B is TRUE
✔️In the domain (input value), we have 3, 6, 7.
Option D is TRUE
Only option C is NOT TRUE.
