So...what? xP This is why Kaddy hates math...
So if the problem was this:
f(x)=5x
g(x)=x^3
The problem to solve would be (fog)(x)=5(x^3). Kaddy gets that much...xP After that, she's completely lost ^^"

5(x)^3 is simple...
x^3's domain is (-∞,∞), and multiplying doesn't do anything to it.
Memorize the information about the parent functions is what we were taught so I know that kind of stuff.

So...you're saying the domain for that isn't equal to 0 again? ugh, I'm so confused...TT.TT -throws away math notebook-

I'm saying that the domain is all real numbers. okay?
Here's an explanation of how I write it.
(Lowest limit in the domain, Highest limit in the domain)
[Lowest NUMBER in the domain, Highest NUMBER in the domain]

Why does Kaddy think that won't be an accepted answer? -sighs- I give up again...-closes notebook and shoves it in my bag- This has made Kaddy unnecessarily confuzzled again >.<" Stupid math...
Or...wait...might an accepted answer for that be that the domain would be this:
Domain = x (isn't equal to) x^3?
Or would it be that it isn't equal to 5?

I would say the domain is either:
-∞≤x≤∞
or what I put.
Or "All real numbers."
I guess Domain=x would work...

I'm trying to use your method. That's why I said.
Domain=x
Because "all real numbers" means if it's a value of x there's a point somewhere on the graph with it as a value.

So you don't need help? Good, that means you're getting it. ^^
I always disliked graphing things.. Well, until it was just sketchy, plotting the major points and being vague from there.
