A. The graph of g(x) is a vertical stretch of f(x) by a factor of 3.

B. The graph of g(x) is a reflection of f(x) across the x-axis.

C. The graph of g(x) is a vertical shrink of f(x) by a factor of 1/3 and a reflection across the x-axis.

D. The graph of g(x) is a vertical stretch of f(x) by a factor of 3 and a reflection across the x-axis.
