Final answer:
The domain of the function is x ≥ 2 and the range of the function is y > 0.
Step-by-step explanation:
The function is defined as y = √(2x - 4). The domain of a function refers to the set of all possible values of x for which the function is defined. For this function, the value inside the square root, 2x - 4, must be greater than or equal to 0. So we set up the inequality 2x - 4 ≥ 0 and solve for x. This gives us x ≥ 2. Therefore, the domain of the function is x ≥ 2.
The range of a function refers to the set of all possible values of y that the function can output. Since the square root of any non-negative number is always positive, the function will output positive values for y. Therefore, the range of the function is y > 0.
