What is the domain and range of this?
Pls help...
On some graphing calculators it doesnt work... Wolfram works but it is unclear.

You know, for any positive number x, we always get y = 1, right?

terenzreignz · Answer

On the other hand, for any negative number x, we always get y = -1

aonz · Answer

terenzreignz · Answer

Well, can it be anything other than -1 and 1? ^.^

aonz · Answer

my textbook says the range is y all real except 1 and -1
