    f(g(x)) well if you had f(3) you would substitute 3 into where you find x so you have f(g(x)) so substitute g(x) where you find x in f(x) this means you are substituting the function g(x) into f(x)

    \[\rm f(g(x)) = {2 \over \large {2 \over x}}\]and\[\rm g(f(x)) = {2 \over \large{2 \over x}}\]Simplify.

    showing that f(g(x)) = x and g(f(x)) = x. that is exactly what you should get well done
