To solve that question we will use the property that says:
[tex]f(x-a)\rightarrow\text{ f shifted ''a'' units to the right}[/tex]Let's say that
[tex]f(x)=4^x[/tex]and
[tex]g(x)=4^{x-3}[/tex]See that
[tex]g(x)=f(x-3)[/tex]Then, to get f we must shift f 3 units to the right!
The correct answer is the letter D.
