Question

which situation could be best modeled with an exponential function?
a the value of a car that loses 6% of its value per year
b the cost to purchase different weights of bananas at a store
c the total number of miles run by a person who runs 8 miles per day

Explanation:

Exponential functions model growth/decay where a quantity changes by a fixed percentage rate over time. Option A involves a car losing a fixed 6% of its value annually, which is exponential decay. Options B and C represent linear relationships: cost of bananas is proportional to weight (linear), and total miles run increase by a fixed 8 miles daily (linear).

Answer:

A. the value of a car that loses 6% of its value per year
