Very confused, and in need of help! I got 10 problems like this...Thanks!
Let f(x) = 6/x1 and g(x)= 1+3/x
Please find the composite function (fog)(x)

Algebra 
Reiny,
I will assume you mean f(x) = 6/(x1) and g(x)= 1+(3/x)
(fog)(x) means f(g(x))
so f(g(x))
= f((1+3/x)
= 6/(1+3/x  1)
= 6/(3/x)
= 6(x/3) = 2x
