Answer:
f(x) =15540(0.95)^x

Explanation:

Given , Micheal bought a car for $15,540.

Rate of depreciation = 5% = 0.05 { To convert a percentage into decimal or fraction , we divide it by 100]

The exponential function used to show depreciation in amount or value ina time period of 'x' is given by :-


f(x)=A(1-r)^x

, where A = Initial value

r= rate of depreciation.

As per given , we have

A= $15,540

r= 0.05

Then , Required function :
f(x)=15540(1-0.05)^x=15540(0.95)^x
