APPLICATIONS OF EXPONENTIAL AND LOGARITHMIC FUNCTIONS

Exponential and logarithmic equations have many uses in the real world. Interest rate calculations on savings, investments, and loans are made using these types of equations. Animal and plant population growth and death rates are calculated and predicted using exponential functions. How fast a liquid cools to room temperature, fluid flow rates through piping systems, random and conditionally random distribution of events are all made using exponential or logarithmic models. In the next two units we will examine some of these applications in a series of problems. We will also define two special functions; the Natural Exponential and the Natural Logarithm and explore how these functions relate to important real-life situations.
