# Ch 13: Exponentials & Logs

Use these video lessons and quizzes to help you understand exponentials and logs. Learn about the properties of exponents and logarithms, solve equations and graph functions.

## Exponentials and Logs - Chapter Summary

In this chapter, you'll learn how to define and discuss the mathematical properties of exponentials and logarithms, graph exponential and logarithmic functions and solve equations related to money and interest. You'll also learn how to define negative and zero exponents, distinguish between linear and exponential growth patterns and describe the dramatic potential of exponential growth. In addition, the instructor will discuss real world exponential growth and the relationship between growth and decay.

During the course of the lesson, you can learn how to locate an exponential equation from a description, graph or point, as well as understand the coefficients of an equation in context. Additional topics include exponential and logarithmic functions and logarithmic scales. At the end of the chapter, you should be able to:

• Identify and work with representations of exponential and logarithmic functions, including algebraic, graphical, numerical and written forms
• Make and use the connections found among functions related to exponential or logarithmic expressions, as well as graphs and symbolic representations of functions
• Understand the relationship between exponential and logarithmic functions
• Use the laws and properties of exponents and logarithms to simplify expressions and solve problems
• Utilize mathematical representations, including graphs, numerical methods and tables, to solve equations, inequalities and systems that include exponential and logarithmic functions
• Model and solve problems involving exponential growth and decay
• Use logarithmic scales, such as decibel and Richter, to describe events and solve problems
• Model and solve finance-related math problems, like compound interest, using exponential and logarithmic functions.

Our concise and engaging video lessons on exponentials and logs are designed to expedite the learning process for busy educators and students. These easy-to-follow presentations are taught by experienced and knowledgeable instructors and are accompanied by lesson transcripts. Each tutorial also includes an online self-assessment quiz that can help viewers determine how well they understood the material.
