Important question: Do you know what the domain and range of a function are in general? edit: I see you are still online looking at this thread. I can help you, I just wanted a simple answer first.

Yes I do Domain:any value of x that this function won't work on? Range: minimum y value? Then anything less than that is out of this function's range. But I don't know how to apply this in brackets with infinities???
