A. Subtract 8 from x and divide the result by 16; f(x) = + 8; g(x) =
B. Subtract 16 from x and divide the result by 8; f(x) = + 16; g(x) =
C. Subtract 8 from x and multiply the result by 16; f(x) = + 8; g(x) = 16(x - 8)
D. Subtract 16 from x and multiply the result by 8; f(x) = + 16; g(x) = 8(x - 16)
