Which statement is true?

A.
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

D

Reason: B(x) = -2x^2 + 4 is a polynomial so its domain is all real numbers. The shown curve A has a left endpoint at (0,2) and continues through (1,3), so its domain appears to be x ≥ 0.
