Course: Intermediate Algebra
Topic: Exponential and Logarithmic Functions
Subtopic: Applications - Exponentials & Logarithms


The applications of exponential and logarithmic functions are extensive, but in this level course we concentration on basic applications. You are expected to attain an exposure to the applications mostly as a motivating factor to solving the exponential and logarithmic equations. We will work on more complicated applications in a precalculus course so here build a firm foundation.


By the end of this topic you should know and be prepared to be tested on:


Terms you should be able to define: exponential growth, exponential decay, half-life

Text Notes

Depending on the text there maybe some applications in this section that you can ignore in this level class. Definitely SKIP any "regression" and "regression analysis".

You should be able to look at graphed data and visually determine if it would be best modeled using a linear, exponential, or logarithmic function, but you do not have know how to find the specific function that would represent the data.

Supplementary Resources

Skim through the various applications of exponential growth and decay described at Exponents in the Real World from Passy's World of Mathematics and read carefully at least a couple that interest you.
