Answer:
Option A is the answer.
Step-by-step explanation:
We have been given the ordered pairs.
The function is a representation
![f:x\rightarrow y](https://tex.z-dn.net/?f=f%3Ax%5Crightarrow%20y)
For a mapping to be a function there should always be a unique value of y for different values of x.
So the mapping :
(-4,-2) (-1,3) (0,3) (5,-6)
3 has two different values hence not a function.
Therefore, Option A is the answer.
