This book covers material that would be covered in a standard algebra course as well as introductions to curve-fitting and data visualization.
Modeling, Functions, and Graphs are the three main concepts that the authors emphasize throughout their textbook. The Rule of Four, which states that all issues should be investigated using algebraic, numerical, graphical, and verbal methods, is used by the authors in their work on modeling and functions.
The authors encourage students to learn algebraic abilities and techniques by putting them in the context of straightforward applications that make use of actual data.
