Answer:
[tex]B.\:\: g(x)=4(2^x)[/tex]
Step-by-step explanation:
The given function is [tex]f(x)=2^x[/tex].
If an exponential function is of the form; [tex]F(x)=a(b^x)[/tex], then [tex]0<\:a<\:1[/tex] will vertically shrink the base function [tex]f(x)=b^x[/tex]
and [tex]a\:>\:1[/tex] will vertically stretch the graph by [tex]a[/tex] units.
The correct answer is B.
