Baked and uncertain about composite functions.

Hey there peoples. I'm high, so I figured this must go here.

I'm not so sure about my structure here.

Let f(x) = (1/x+1)
and g(x) = (x/x-1)

Help me find f(g(x))? g(f(x))? f(g(f(x)))? f(g(x+h))?

Thank you, escape artists.

 

Well, f of g of x / f(g(x)) means multiply the two, so its like 1/x+1 x x/x-1. I'm pretty sure thats how you do it, if that was even what you were asking. If not, sorry!

g(f(x)) - this should be the same as the first equation
f(g(f(x))) - multiply the answer from the first one by f(x)
f(g(x+h) - f(x) times g(x+h)? I'm not sure here.. whats the h?

That was my best guess at the stuff dude, its been awhile
