I'm having trouble figuring the range of this function:

y = [square root] (x-2) / (6+x) [/square root]

I know that the horizontal asymptote is y = 1, so there would be some restrictions there. I am just not sure how to use that info to find the range.

Thank you!

The answers are y > 0 and y < 1 .. I graphed it and I can see how it works out, just need some explanation please
