Explanation:
The expression exponential growth is applied to a magnitude such that its variation in time is proportional to its value, which implies that it grows faster and faster in time, according to the equation:
![f(x)=ab^(x)](https://img.qammunity.org/2020/formulas/mathematics/high-school/nr8rdhlo5op759jp7qs83n4f7iw5baa06j.png)
So, we can modeling an equation that describes the increasing of the population of Madison.
The town of Madison has a population of 25,000. The population is increasing by a factor of 1.12 each year.
![p(t)=p(0)e^(rt)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mmf4wzhmp5pl073t1ges3d9gdk8a0gttku.png)
Where p(t) is the population increase in a t years, p(0) is the initial population, r is the increasing factor, and t the amount of years elapsed.
So, we obtain:
![p(t)=25000e^(1.12t)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xkpu04tkst4jkzkjpzi7v53z6p8h13idvv.png)
