On a piece of paper, graph f(x) = 5. (0.4)* then determine which answer
choice matches the graph you drew.

The graph in the attached figure

Step-by-step explanation:

we have

This is a exponential function of the form

where

a is the initial value or the y-intercept of the exponential function

b is the base

b=(1+r)

r is the percent rate of change

we have

---> is a decay function

To draw the graph on a piece of paper we will plug in the values of x in the function.

so

For x=-1 --->

For x=0 --->

For x=1 --->

For x=2 --->

For x=3 --->

we have the points

(-1,12.5),(0,5),(1,2),(2,0.8),(3,0.32)

Plot the points in a coordinate plane to graph the function

using a graphing tool

The graph in the attached figure

Is a decreasing function, because as x increases (reading from left to right), y decreases

the answers c

-4
