Logarithmic Functions

Success Criteria

At the end of this chapter, students are able to:

1. 1. Convert equations from indice form to logarithmic form and vice-versa.

   2. Apply the Product Law and Quotient Law.

   3. Apply the Power Law.

   4. Apply the Change-of-Base Law & Reciprocal Law.

   5. Solve logarithmic equations.

   6. Sketch logarithmic graphs.

   7. Apply logarithmic functions to model real-world problems (AO2).

Introduction

In our study of functions, the previous chapter explored exponential functions. However, every function needs an inverse function (an undo button). The inverse function to exponential is the logarithmic function.

Next: Let's begin by learning how to convert indice form to logarithmic form.
