Course: College Algebra
Topic: Exponential and Logarithmic Functions
Subtopic: Logarithmic 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 logarithmic 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: logarithmic function, common logarithm, natural logarithm
