Answer:

3rd option:

D: [0, ∞)

R: [2, ∞)

Explanation:

the easiest way to answer this question is to graph it but remember, you cannot use any negative values for 'x' because negative square roots are not real numbers

some good values to use when creating an x-y table would be:

0, 4, 16, 25, etc.
