Answer:

You are correct it is not a function

Explanation:

The reason is if you look in the x place (x,y) that is the input in this situation and you know a function can only have one output for each input and in this case we see that -3 has two outputs 1 and 5. Also -3 and 3 are two different inputs so if it was a debate between those two it would be a function.
