Select the correct answer.
Consider the graph of function g.

A parabola labeled lowercase g declines through the points (negative 4, 4), (negative 3, 2 point 2), (negative 2, 1), (0, 0), (2, 1) and (3 point 5, 3) on the x y coordinate plane.

If f(x) = x2, which equation represents function g?

A. g(x) = f(2x)
B. g(x) = f(4x)
C. g(x) = 2 f(x)
D. g(x) = f(1/2x)
