Consider the function f(x) = x2 and the function g(x) shown below. How will the graph of g(x) differ from the graph of f(x)? g(x) = 3·f(x) = 3x^2
A.
The graph of g(x) is the graph of f(x) shifted up 3 units.

B.
The graph of g(x) is the graph of f(x) compressed vertically by a factor of 1/3.

C.
The graph of g(x) is the graph of f(x) shifted to the right 3 units.

D.
The graph of g(x) is the graph of f(x) stretched vertically by a factor of 3.
