Final answer:
The domain of the function y = 3/(x - 1) is x ≠ 1.
Step-by-step explanation:
The domain of a function is the set of all possible input values (x-values) for which the function is defined. In the function y = 3/(x - 1), the only value that is not allowed is when the denominator (x - 1) becomes zero. So, we need to find the x-value that makes the denominator zero. In this case, x = 1. Therefore, the domain of the function y = 3/(x - 1) is x ≠ 1.
