Considering the definition of exponential function, the value of the car is 11,287.25 dollars.
<h3>What is exponential function</h3>An exponential function is one in which the independent variable x appears in the exponent and has a constant a as its base. Its expression is:
f(x)= aˣ
Being a a positive real, a > 0, and different from 1, a ≠ 1.
When 0 < a < 1, then the exponential function is a decreasing function and when a > 1, it is an increasing function.
<h3>What is the price of the car</h3>In this case, the value of that car depreciates based on the function f(t)=12,000× where t is measured in years after purchase.
After 3/2 years, the value of the car is calculated as:
f(3/2)=12,000×
Solving:
<u><em>f(3/2)= 11,287.25</em></u>
Finally, the value of the car is 11,287.25 dollars.
