I think it is {-4, -5, 2, 2} because you can have multiple y values so two 2's would be okay.

Just get the y term (x,y) and y is the range.

oooohhhh Thank you!!!!

however if it is for domain like x, well just think the same (x,y) just get the x terms, however, remember that if you have 2 x's that's not a function.
2,1 can't have 3,1 that's not a real function, it doesn't pass the vertical line test.

But no problem ;p
