Question

Problem attached. Dealing with F of G

Answer 1

(f o g) -> f(g(x))
so plug in (14/x) for x into x/(x+1)
do you know how to do that? :)

Answer 2

once you do that, multiply top and bottom by x
don't forget that it would be distributive on the denominator
then you'll get the answer you need

then for domain, know that denominators cannot equal zero

Answer 3

14/(14+1/x) ?

Answer 4

close! :)

it would be 14/(14+x)
