The study of exponential and logarithmic functions requires a thorough understanding of several important concepts that have appeared earlier in this course. In particular, you’ll need to be able to use the properties of exponents to rewrite expressions containing them and understand the relationship between corresponding input and output values in a function.

This review section contains concepts from earlier sections in this text. Review them carefully to refresh your understanding before beginning your study of these two, new toolkit functions.

Warm up for this module by refreshing important concepts and skills you’ll need for success. As you study these review topics, recall that you can also return to Algebra Essentials any time you need to refresh the basics.
