Two common types of mathematical models are Exponential Growth: y = a ebx, b 0. Exponential Decay: y = a e-bx, b 0. During the 1980s the population of a certain city went from 100,000 to 205,000. Populations by year are listed in the table below. This data is approximated well by the exponential growth […]

hen looking at population growth over a short period of time it may appear to follow a linear function. Use theU.S. Population Clockand record the U.S. population at regular intervals such as every 1/2 hour for a few hours or every 24 hours for a week. Determine the best function for this data. While a […]

Some of the things that exponential growth is used to model include population growth, bacterial growth, and compound interest. If you are lucky enough to be given the initial value, that is the value when x = 0, then you already know the value of the constant C. The only thing necessary to complete the […]

Real World Application of Exponential Growth Exponential growth functionsare often used to model population growth. Below is an interactive demonstration of the population growth of a species of rabbits whose population grows at 200% each year and demonstrates the power of exponential population growth.

As a population grows, its additional members produce virile offspring, such that the more a population grows, the faster it continues to grow. This exponential growth follows a continuous compounding rate that can lead to alarming growth patterns, such as a single bacterium growing to several million bacteria within 24 hours. Before calculating a future […]

Geometric growth models simulate the population changes of a population where birth can only take place at one specific time while deaths occur continuously and the growth is at a constant rate. This type of growth produces a graph in which the population increases all at once at set intervals while the remaining time the […]
