Answer 2

1) Function

2)Function

3) Not a function

4) Function

Explanation:

The same process applies from the previous one, the x values can not repeat if it is a function.

For the first one the x values do not repeat only the y's. Therefore it is a function.

For the second one the x values do not repeat either, therefore it is a function.

For the third one the x values repeat multiple times making it not a function.

For the fourth one the x values do no repeat making it a function.
