What is the function of appendices in Book 3-2?

The function of appendices in Book 3-2 is to provide supplementary materials and reference resources. Appendices are designed to enhance the main content of the book by offering additional information that supports the topics discussed in the chapters. This may include charts, graphs, detailed explanations, sample problems, or any other relevant data that can aid the reader’s understanding and provide context beyond what is presented in the main text.

By including these materials, the appendices serve as a valuable resource for readers looking to deepen their comprehension of the subject matter or needing quick access to specific information without searching through the main chapters. Each of the other options does not accurately describe the function of appendices. They do not introduce the book, solely include exams, or summarize chapters, as these tasks are typically covered elsewhere in the text.
