I thought I was right here - I chose these answers because A. When you square root the y^3 it gives the answer to be + or - so it's not a function, same thing with B.

The last two, I did the math and it gave me a y input value. So I decided they were functions.

However it told me I was incorrect. At least one of them is wrong but I'm not sure which one - anyone help?
