Select the correct answer. Consider the function f(x) = 2x and the function g(x) shown below. How will the graph of g(x) differ from the graph of f(x)?
g(x)=2f(x)=2(2^x)

A.
The graph of g(x) is the graph of f(x) shifted up by a factor of 2.
B.
The graph of g(x) is the graph of f(x) shifted to the right by a factor of 2.
C.
The graph of g(x) is the graph of f(x) stretched vertically by a factor of 2.
D.
The graph of g(x) is the graph of f(x) stretched horizontally by a factor of 2.
