How To Write An Equation In Exponential Form

Introduction. Exponential functions can be used to model growth and decay. For example, the world’s human population is growing exponentially as can be seen in the following graph.

• Exponential functions are ever-increasing so saying that an exponential function models population growth exactly means that the human population will grow without bound.

• That is not sound reasoning, as the human population is affected by various factors among these are access to resources such as food, water, and shelter.

• It is the shortest way of expressing a large number. It is also known as the Scientific Notation.
