Question 433512
The given function f is one-to-one. 

{{{f(x)=(ax+b)/(cx+d)}}}

a) Find the domain of f
All Real Numbers except x = -d/c
------------------
b) Find f'
f'(x) = [(cx+d)a-(ax+b)c]/(cx+d)^2
------------------
c) Find the range of f
All Real Numbers except y = a/c
------------------------------------ 
d) If c is not equal to 0, under what conditions on a, b, c, and d if f=f'
I'll leave that to you.
Cheers,
