To complete the table representing the value of a car after x years, typically, we would use a formula for depreciation. A common model for car depreciation is that a car loses a fixed percentage of its value each year. For this example, let's assume the car starts with an initial value of $20,000 and depreciates at a rate of 15% per year.

Using the formula for depreciation:

f(x)=P(1r)x

where:

  • P is the initial value of the car (here, 20000),
  • r is the rate of depreciation (15% or 0.15),
  • x is the number of years.

Let's calculate f(x) for different values of x:

  1. For x=0: f(0)=20000×(10.15)0=20000×1=20000.00

  2. For x=1: f(1)=20000×(10.15)1=20000×0.85=17000.00

  3. For x=3: f(3)=20000×(10.15)3=20000×0.85320000×0.614125=12282.50

  4. For x=5: f(5)=20000×(10.15)5=20000×0.85520000×0.443705=8874.10

  5. For x=8: f(8)=20000×(10.15)8=20000×0.85820000×0.272490=5449.80

Now we can fill out the table:

The completed values are:

  • For x=0: $20000.00
  • For x=1: $17000.00
  • For x=3: $12282.50
  • For x=5: $8874.10
  • For x=8: $5449.80
