Question 650142
Alright, some other tutor correct me in I am wrong, but I believe I can do this:

To find f(f) we replace f (x+1) with all of the x's in the f (x+1) equation:

x+1+1

we get x+2 is your f(f)

Do get the domain, we set the denominator of the fraction to 0

[-1]+1=0

The domain in interval notation is (-infinity,-1) union (-1, infinity)

The range, you set the numberator to 0

[1]-1=0

The range in interval notation is (-infinity,1) union (1, infinity)

Hope this helps!
