Division by zero is undefined so x-1 cannot equal zero and thus x cannot equal 1.

So the domain is all real numbers except 1

Answer:  All real numbers except 1

Explanation:

The domain is the value that x can take from a given function and codomain is the value of y from a function.The range of a function is subset of codomain which also the set of values y can take.

Here, we can not take the value of x as 1 otherwise the function will become not defined
