a. The vertex is (-2, 4), the domain is all real numbers, and the range is y ≥ 4.

b. The vertex is (-2, 4), the domain is all real numbers, and the range is y ≤ 4.

c. The vertex is (2, 4), the domain is all real numbers, and the range is y ≤ 4.

d. The vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4.

    I think the correct answer from the choices listed above is option D. For the function f (x) = (x - 2) 2 + 4, the vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4. The domain is all x-values available for the function and the range are the y values and in this case it should be greater than or equal to 4. Hope this answers the question.
