"Math Dialogue: Functions" is a very gentle introduction to the concept of the function, written in form of a dialogue. This is an ideal approach for students who would like to understand the basics, but are unsatisfied with the common textbook format. The book contains three lessons. The function, as well as related concepts such as the domain and the graph, are introduced in lesson one. Lesson two consists of a detailed look at linear functions. The final lesson deals with all aspects of quadratic functions. Whether you've been struggling or you just want to know what's going on - this book is for you.
