Consider the exponential function

f(x)=19,000•0.96x, which models the value of Mark’s car, where x represents the number of years since he purchased the car.

What is the approximate value of Mark’s car after 7 years rounded to the nearest dollar?

a $14,278
b $14,000
c $14,277
d $14,280

Given:

The given function which models the value of Mark’s car, where x represents the number of years since he purchased the car.

We need to determine the approximate value of Mark's car after 7 years.

Value of the car:

The value of the car after 7 years can be determined by substituting x = 7 in the function , we get;

Rounding off to the nearest dollar, we get;

Thus, the approximate value of Mark's car after 7 years is $14278.

Hence, Option a is the correct answer.
