You stated the domain, it asked for the range
range:
y < 3 OR y > 3 , y ∈ R
or
range is {y| y ∈ R, y ≠3 }
I will let you change that to interval notation, not really familiar with that notation. We did not have that in the "olden days" when I was teaching.
Let f(x)=(3x-7)/(x+1)
What is the range of f?
Answer in interval notation.
(The domain is (-inf,-1) U (-1,inf)
