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
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
Applications In this section we will look at a couple of
applications of exponential functions and an application of logarithms.
