SOLUTION: f(x)= 6/x+3 g(x)= 2/3x find (f o g)(x) and (g o f)(x) I don't think I know how to set this up when there are fractions involved. Please help, if possible.

Question 410709: f(x)= 6/x+3 g(x)= 2/3x find (f o g)(x) and (g o f)(x) I don't think I know how to set this up when there are fractions involved. Please help, if possible.

f(x)= 6/x+3
g(x)= 2/3x
-----------------
(f o g)(x)
= f[(2/3)x] = 6/[(2/3)x+3]
------------------
(g o f)(x)
= g[6/(x+3)]
----
= (2/3)[6/(x+3)]
---
= 4/(x+3)
