Question

You know that:

f(g(x))=ln2+x
g(f(x))=2x

What is the domain?

Answer 1

do you know where defined the logarithm (natural) function ?

Answer 2

I started out with f(x)=ln(2x) and g(x)=e^x. The question was "What is the domain for the functions f(g(x)) and g(f(x))?"

Answer 3

Now that I´ve received my answers I don´t know how to continue.
