Answer:
all real numbers except 1
Explanation:
The objective is to determine the domain of f(x) =

The domain relates to the set of all possible values of x where the given function defined and the codomain is the target set into which the function is normally defined to map elements of the domain which is defined by y.
From the question:
If we divide zero by equation, the result will be undefined. Thus, x will never be equal to zero or one. Hence, the domain is all real numbers except 1.
