The value of the car after four year is $9396.108 .

Option (b) is correct i.e about $9400 .

Step-by-step explanation:

The exponential decreasing function is given by

Where a is the initial value , r is the rate of interest in decimal form and t is the time in years .

As given

Mr.henry buys a car for $18,000. the value of the car decreases about 15% each year. after 4 years .

a = $18000

15% is written in the decimal form .

= 0.15

t = 4 years

Putting all the values in the formula

y = $9396.108

Therefore the value of the car after four year is $9396.108 .

Option (b) is correct i.e about $9400 .
