----- (greater than or equal) 0
Do the problem I get x=8 and x=7
I graph it, and test it, and am wondering what exactly is the rule for when to put () or 
My understanding is that since it is a (greater than or equal) sign it should be 
But, the answer states it is (7,8] and Im not sure why.
I read something that if a number in the solution makes the denominator 0 then you must include it with () and I would have gotten it wrong as I was going to enter it as [7,8]
Is it basically this? if a number that is the solution on my graph makes the original equations denominator 0 then that number will have a () by it?
Maybe someone can dumb it down for me
