Luis has saved $6. he doubles the amount he saves each week. does this represent an exponential function? complete: represent an exponential function , because his savings increase by a you so much in advanced ?

This does represent an exponential function , because his savings increase by a constant rate

Step-by-step explanation:

Let

x -----> the number of weeks

y ----> the amount saved

In this problem we have a exponential function of the form

where

a is the initial value

b is the base

r is the rate of change

where

---- because he doubles the amount each week

---->

substitute

therefore

This does represent an exponential function , because his savings increase by a constant rate
