Given the composition h ( x ) = f ( g ( x ) ) , if h ( x ) = 6 /x + 3 and g ( x ) = x + 3 , find the function f ( x ) .

Question

Answer 1

These us3d to confuse me, too!

Remember that f(3) would mean replacing x with 3 in the function, so f(g(x)) is replacing x with x + 3.

I bet you can tell me which f(x) would result in 6/x + 3 if you replaced x with x + 3.
