## Understanding Exponential & Logarithmic Functions - Chapter Summary

This collection of calculus study resources covers essential concepts related to logarithmic and exponential functions. Inside the chapter, you'll find simple lessons that walk you through the steps needed to solve a variety of exponential and logarithmic function problems. You'll also examine concepts such as the change-of-base formula, the population dynamics problem, transformation and logarithmic properties. After completing the chapter, you should be able to:

• Define the terms exponential function, logarithm, natural log and natural base e
• Differentiate between exponential grown and decay
• Understand the transformation of exponential functions
• Write a logarithmic function's inverse
• Evaluate logarithms and recognize their properties
• Apply the change-of-base formula for logarithms
• Practice solving exponential and logarithmic equations
• Solve the population dynamics problem to calculate rate and exponential growth

To practice solving problems, take the self-assessment quizzes that follow each lesson. This way, you can be sure you fully understand these concepts and can solve these types of problems for a test. You'll be able to keep track of your progress throughout the chapter on your course Dashboard, which also allows you to jump to specific lesson topics. Feel free to submit questions to our instructors if you need extra help. Finally, the lesson material is available 24/7 and accessible on any device that has an Internet connection.
