Final answer:
The domain of the function is x ≥ 2 and the range is y ≥ 0.
Step-by-step explanation:
The domain of a function is the set of all possible input values, while the range is the set of all possible output values.
For the function y = √(2x - 4), the domain is determined by the values that satisfy the square root.
We set 2x - 4 ≥ 0, because the square root of negative numbers is not real.
Solving this inequality, we get x ≥ 2.
The range, on the other hand, is determined by the possible values of y.
Since the square root function output positive values, the range is y ≥ 0.
