Consider the function graphed below.

A curve labeled lowercase f extends linearly from (negative 7, 2), (negative 6, 2), and (negative 4, 2) and then rises through (0, 3), (1, 4), and (2, 5) on the x y coordinate plane.

If f is translated 4 units down to create g, which function represents g?

A.
g(x) = f(x + 4)
B.
g(x) = f(x - 4)
C.
g(x) = f(x) + 4
D.
g(x) = f(x) - 4
