Another Look at Exponential Functions and What They Mean! Exponent Guy
An antique coin appreciates in value the older it gets. The following data shows that the value of a certain coin for every year since it was purchased. a) Using a graphing calculator with Diagnostics turned on, determine the function for this relationship. a initial value, when x = 0 b common ratio (app by 15%)
Now if we take into consideration these two points (0 , 3) and (5, 6) as two points on the curve and replace the doubling effect as 2 for the base, how else can we represent this scenario? 5 is the time it will take to double. 3is the initial value when x = 0 2 is the base to show the price is doubling.

More Examples: 1. An investment triples every six years. If you invest $2500, how much will it be worth after 25 years? After 25 years, the $2500 investment would be worth $243, 189.73 2. A house appreciates by 10% every 4 years. How much would a $100,000 house be worth in 20 years? After 20 years, the house could sell for $161, 051.
