OK, The question states...
Find the domain of each function h(x) by studying the domain of f(x) and g(x).

h(x) = f(x) + g(x) where f(x) = square root of (x-3) amd g(x) = x squared -4

(sorry about the words couldn't find the square root symbol or the squared symbol.)

So. In the lesson (online) it just says the domain is this and the domain is that. But it doesn't show how you are supposed to find the domain of a function. I am sure I am missing something but I have been working on this for 2 days and trying all kind of stuff and I am totally lost.

I just need to know how to find the domain.

PLEASE HELP.
I wish I had work to show you but I don't.
