Consider the function f(x)=10^x and function g(x)=f(x+4). How will the graph of function g differ from the graph of function f?

A. The graph of function g is the graph of function f shifted 4 units to the left.

B. The graph of function g is the graph of function f shifted 4 units to the right.

C. The graph of function g is the graph of function f shifted 4 units up.

D. The graph of function g is the graph of function f shifted 4 units down.
