The rate at which the value of the car decrease is an illustration of depreciation
The function is given as:
[tex]y = 12000 * 0.9^x[/tex]
The term "Right now" means x = 0.
So, we have:
[tex]y = 12000 * 0.9^0[/tex]
[tex]y = 12000[/tex]
Hence, the worth of the car right now is $12000
The function is given as:
[tex]y = 12000 * 0.9^x[/tex]
One year ago means x = -1.
So, we have:
[tex]y = 12000 * 0.9^{-1}[/tex]
[tex]y = 13333[/tex]
Hence, the worth of the car one year ago is $13333
