The function f(x) = 550(1.035)x models the amount of money in a certificate of deposit after x years. How much money will there be in 9 years?
The function f(x) = 125,000(0.99)x, where x is the time in years, models the population of a city. What will the population be in 6 years?
You decide to buy a used car that costs $12,000. You’ve heard that the car may depreciate at a rate of 15% per year.
Write an equation to represent the price of the car, f(x), in terms of the years since its purchase, x.
