Find the domain and the range of each of the following real function: 
Given: 
Need to find: Where the functions are defined.
The condition for the function to be defined,
⇒ 
⇒ 
So, the domain of the function is the set of all the real numbers greater than 1.
The domain of the function, Df(x) = (1, ∞).
Now putting any value of x within the domain set we get the value of the function always a fraction whose denominator is not equals to 0.
The range of the function, Rf(x) = (0, 1)
