Answer:
Exponential functions can be examples such as population growth or decay, interest on savings accounts or investments, carbon dating, and finding an approximate time of death.
Two common examples of exponential functions are:
- Changes in populations.
- Change in value of purchase goods (like cars)
What is an exponential function?
An exponential function is something of the form:
f(x) = A*(1 + r)^x
Where A is the initial value, x is the variable, and r is the rate of growth/decay.
- if r > 0, the function represents an exponential growth.
- if r < 0, the function is an exponential decay.
So one example of exponential growth is the growth of a population of something, like bacteria. For example, if you know that the population increases a 20% per week, and has an initial population of P, the population equation is:
f(x) = P*(1 + 20%/100%)^x
Where x is the number of weeks.
Another example is the value of something you purchased, for example, a car, assume that you purchased for a price P, and the value decays at a rate of 15% per year, then the value function is:
f(x) = P*(1 - 15%/100%)^x
Where x is the number of years, this would be an exponential decay.
