Final answer:
The domain of the function y=3√x-1 is 0≤x<∞.
Step-by-step explanation:
The domain of the function y=3√x-1 is 0≤x<∞, which means that any non-negative value of x is within the domain. Since the function involves a square root, x must be greater than or equal to 0 to avoid taking the square root of a negative number. Additionally, there are no restrictions on the upper limit of x, so x can be any positive number.
