wow, a simple thanks would have been more than enough ...
I fixed the -2 like ten minutes ago
and ( means it can never actually equal - infinity but it's close to it
[ means it can be the actual number (-2) and still be a correct function
Yeah, I should have mention the brackets in the answer (-infinity, -2] ... like I said, it's been years.
