Which is the graph of f(x) =4(1/2)^x
Nuetrik [128]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

f(x)=4(\frac{1}{2})^{x}

This is a exponential function of the form

y=a(b)^{x}

where

a is the initial value

b is the base

r is the rate

b=1+r

In this problem we have

a=4 ----> initial value (y-intercept)

b=1/2

so

1+r=1/2

r=1/2-1=-1/2

r=-0.5=-50% ----> is negative because is a decrease rate

using a graphing tool

The graph in the attached figure
