the temperature of a hot liquid is 100 degrees. the liquid is placed in a refrigerator where the temperature is 40 degrees. it cools to 90 degrees in 5 minutes. Find an exponential function to model this data

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