Answer:

The graph in the attached figure

Step-by-step explanation:

we have

[tex]f(x)=2(4^x)[/tex]

This is a exponential function of the form

[tex]f(x)=a(b^x)[/tex]

where

a is the initial value

b is the base

r is the rate

b=(1+r)

In this problem we have

[tex]a=2\\b=4\\r=b-1=4-1=3=300\%[/tex]

For x=0

[tex]f(0)=2(4^0)[/tex] -----> [tex]f(0)=2[/tex] ---> y-intercept or initial value

For x=1

[tex]f(1)=2(4^1)[/tex] -----> [tex]f(1)=8[/tex]
