Domain in Set-builder Notation
Given 2/(x - 2) and (x - 2)/(x + 2), find the domain. Express domain in set-builder notation.
For 2/(x - 2):
x - 2 = 0
x = 2
D = {x | x cannot = 2}
For (x - 2)/(x + 2):
x + 2 = 0
x = -2
D = {x | x cannot = -2}

I don't know how to use LaTex. By the way, I don't have a computer or a laptop. Learning LaTex with a cell phone is a nightmare in terms of typing all the details carefully.

Re: Domain in Set-builder Notation
Fair point. At the top of each post there's a list of symbols you can copy and paste. ≠ is available there. Does your phone allow you to copy any of those.
Whatever, I was happy with your answer as it had the essential bits.

I see the symbols at the top of each post. My cell phone does allow me to copy and paste the symbols here but I can copy each symbols found, for example, in Wikipedia and then post here.
