I THINK it’s Z
Why? Because the y values aren’t repeating.

Answer:

W

Explanation:

A function must have the same output for every input, so if a table were to have -2 twice it must have the same output for that (like -2,3 and then again -2,3 if it were to repeat) I'm not the best explainer but for each input there must be exactly one output.
