Summary

New Features

• Mathematical Modeling and Data Analysis: A focus on mathematical modeling and data analysis, specifically establishing a step by step process for understanding word problems and gathering the data from said problems.
• Objective Based Learning: Introductory section objectives have been expanded to include the "what and why" of the objectives, followed by icons within the text identifying the specific areas of focus. A summary of chapter objectives will now be featured in the chapter summary material.
• Graphical Interpretation: Throughout both examples and exercises, this feature focuses on the importance of learning to read and extract data from a given graph. This is developed by first presenting a graph and using a problem solving approach to read said graph. This focus aids in conceptualizing functions and building mathematical models.
