Question 1113335: Find the domain of f(x) = √(x-1)/(x-1)

(1) x=1 is not in the domain, because it makes the denominator equal to 0.
(2) In the numerator, x-1 has to be 0 or positive, because the square root of a negative number is not a real number; that means x has to be greater than or equal to 1.
Since x=1 is not in the domain, the domain is x > 1.
