You can navigate through this E-Book using the menu to the left. For E-Books that have a Chapter/Section organization each option in the menu to the left indicates a chapter and will open a menu showing the sections in that chapter. Alternatively, you can navigate to the next/previous section or chapter by clicking the links in the boxes at the very top and bottom of the material.
Also, depending upon the E-Book, it will be possible to download the complete E-Book, the chapter containing the current section and/or the current section. You can do this be clicking on the E-Book, Chapter, and/or the Section link provided below.

In this chapter we are going to look at exponential and
logarithm functions. Both of these
functions are very important and need to be understood by anyone who is going
on to later math courses. These
functions also have applications in science, engineering, and business to name
a few areas. In fact, these functions
can show up in just about any field that uses even a small degree of
mathematics.
Many students find these to be difficult functions to deal
with, especially logarithms. This is
probably because they are so different from any of the other functions that
they’ve looked at to this point and logarithms use a notation that will be new
to almost everyone in an algebra class.
However, you will find that once you get past the notation and start to
understand some of their properties they really aren’t too bad.
Here is a listing of the topics covered in this chapter.
Exponential Functions
In this section we will introduce exponential
functions. We will be taking a look at
some of the properties of exponential functions.
Logarithm Functions
Here we will introduce logarithm
functions. We be looking at how to
evaluate logarithms as well as the properties of logarithms.
Solving Exponential Equations
We will be solving equations that contain
exponentials in this section.
Solving Logarithm Equations
Here we will solve equations that contain
logarithms.
Applications
In this section we will look at a couple of
applications of exponential functions and an application of logarithms.
