Select the correct answer.
The function f(x) is given by the table of values.

x 1 2 3 4
f(x) 1 8 27 64
If f(x) is shifted 4 units up to obtain g(x), which table of values represents the function g(x)?


x 5 6 7 8
g(x) 5 12 31 68


x 1 2 3 4
g(x) 5 12 31 68


x 5 6 7 8
g(x) 1 8 27 64


x 1 2 3 4
g(x) 4 32 108 256
