Question

If f(x) = x/(2x - 1) and and g(x) = (x + 1)/(- x) then find g(f(x)) and state the domain of this composition function .

Answer 1

Explanation:

First thing to do is insert f(x) in for x in g(x) to make g(f(x))

`g(f(x)) = ((x)/(2x - 1) + 1) / ( - (x)/(2x - 1) )`

f(x) is in the domain of g(x) which create the composition function.
