In this table, is y a function of x?

x | 1 | 2 | 3 | 4 |
y | 1 | 8 | 27 | 64 |.... and so forth..

the equation is y=x^3(cubed)

on the answer key it says that y is NOT a function of x.... but i dont see why not....
can someone please explain this to me?

Your answer key is wrong, or you are not reading the right answer.
From the data you presented above y = x^3 is OK.

err...

It looks like its a function of x maybe there's one that's not. That would be my best guess.
