Course: College Algebra
Topic: Exponential and Logarithmic Functions
Subtopic: Exponential Functions and Graphs


Since much of the material in this lesson is review from an intermediate algebra course, our focus here will be to expand on the basic topics, bump-up the level of difficulty, and get exponential functions down really well. As you work through the material, try to do what you can algebraically as well as take advantage of technology where appropriate.


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


Terms you should be able to define: exponential function, natural exponential constant "e"

Mini-Lectures and Examples

STUDY: Exponential Functions and Graphs

Supplementary Resources

Watch Dr. Albert Bartlett's Arithmetic, Population and Energy video which examines the arithmetic of steady growth in a finite environment. These concepts are applied to populations and to fossil fuels such as petroleum and coal. Although first given over 40 years ago, this presentation is highly recommended.
Eight 10-minute video segments: 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8

e - The Story of a Number
by Eli Maor is great reading!

Supplemental Resources (optional)

If you need supplemental tutorial videos with examples relevant to this section go to James Sousa's MathIsPower4U and search for topic: "Introduction to Exponential Functions". Some will be review material from Intermediate Algebra and some will be the more challenging level of this course.
