f(x) = x + 1/x , g(x) = x+17/x+2

a) (f o g)(x)

b) (g o f)(x)

c) (f o f)(x)

d) (g o g)(x)

and domains for all...which I think is the hardest part.

So I'm not sure if this is right but let me know if I'm doing it wrong.

For the functions for example a) I would put F(g(x)), g(x) = 1+17/x+2 therefore f(x+17/x+2) = (x+1/x +17/ x+1/x + 2)...and domain I'm not sure what to write other then it can't be divided by 0 but I need to be sure if the function is correct before I can find the domain. THANKS.

Interval notation for domain.

EDIT: Sorry I put it in the wrong section, :X
