Answer:
Non-function
Step-by-step explanation:
A function is a relation from a set of inputs to give a set of outputs.
In a function a particular input can only result in one output only.
Which means one input cannot generate more than one output.
For the given question;

We can observe that the output at the input -6 is more than one.

A single input -6 produces two outputs 3 and 2.
So, since one input produces more than one output, the data is not a function.
Therefore, It is not a function
