    Please Help Me Solve this composite function Problem

    Find the function f(g(x)) and simplify your result where f(x)= 2/x and g(x)=x/x-2?

    Just to let you know that f(x) is a fraction 2 at the top x on the bottom and g(x)= x is on the top and x-2 is on the bottom.

    OK it's a question now.

    f(g(x)) = f\left(\frac{x}{x-2}\right) = \frac{2}{\left(\frac{x}{x-2}\right)}

    You should be able to take it from here.

    Hope this helps,
    pomp.
