What is the domain of (fg)(x)?
Your question doesn't make sense so I assume this notation is new to you.
You probably mean the domain f(g(x)) and you got it from a different question.
The domain is all the values that x is allowed to be.
(The range would be all the values that y is allowed to be.)
I hope this helps. You can ask questions like this on the back of other posts if you want to.
