Understanding ray diagrams for concave lenses

Hey guys,

So some friends and I are studying for a test and we came across this question. I've absolutely no idea what the answer is simply because every website I've found only shows parallel rays and a ray going through the centre of the lens. It's incredibly aggravating.

Anyway here's the question -



Ray X became Ray Z when passing through the lens. Which does Ray Y become?

As I said, every website/textbook/youtube video skips this info so I don't have a guess. Can you please not make me work for the answer. I'll understand it if you just tell me. I don't want to hate studying - I just want to know.

Thank you
