The domain of function B is all real numbers greater than 0, and the domain of function A appears to be all real numbers.

B.
The domains of function B and function A appear to be the same.

C.
The domain of function B is all real numbers, and the domain of function A appears to be all real numbers greater than or equal to 2.

D.
The domain of function B is all real numbers, and the domain of function A appears to be all real numbers greater than or equal to 0.

Answer: D.

Reason: y = -2x^2 + 4 is a polynomial so its domain is all real numbers. The graph of function A "starts at (0,2)" and then continues through (1,3), so A appears to be defined only for x ≥ 0. Therefore B: all real numbers, A: all real numbers ≥ 0 — option D.
