y=-2x^2+4
A curve starts at (0, 2) and passing through (1, 3).

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 is a quadratic y = -2x^2 + 4 so its domain is all real numbers. The graph of A has a left endpoint at x = 0 and then continues to the right (it passes through (1,3)), so A's domain appears to be x ≥ 0.
