Question

Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car after x years, which function represents the car’s value? (HINT: Problem about annual depreciation)

Answer 1

F(x)=20,000+.15x and plug years for x

Answer 2

Hi there,

100% - 15% = 85%
85% = 85/100 = 0.85

This is your factor of depreciation
The power it is raised to equals the years
20,000 x 0.85^3
= 12282.5

I hope my answer has come to your help. Thank you for posting your question here in Brainly.
