Various factors limit the rate of growth of a particular population, including birth rate, death rate, food supply, predators, and so on. This is unrealistic in a real-world setting. We recommend using aĪuthors: Gilbert Strang, Edwin “Jed” Herman One problem with this function is its prediction that as time goes on, the population grows without bound.

In this section, we examine exponential growth and decay in the context of some of these applications. From population growth and continuously compounded interest to radioactive decay and Newton’s law of cooling, exponential functions are ubiquitous in nature. Exponential growth and decay show up in a host of natural applications. One of the most prevalent applications of exponential functions involves growth and decay models. 2.8.4 Explain the concept of half-life.2.8.3 Use the exponential decay model in applications, including radioactive decay and Newton’s law of cooling.

2.8.2 Explain the concept of doubling time.If k < 0, or equivalently, r < m then more people die on average than are born, so that the population will shrink and (eventually) go extinct. when the per capita birth rate, r exceeds the per capita mortality rate m. 2.8.1 Use the exponential growth model in applications, including population growth and compound interest. The population will grow provided k > 0 which happens when r m > 0 i.e.
