For this edition the authors have increased the use of applied examples and exercises, which lets students to focus on real-life applications of mathematics. All the applications are titled and incorporate source-based data, allowing instructors and students to easily identify problems of interest. Many of the applications feature mathematical models based on real data or real data in table form, thereby providing students with increased opportunities to use, construct, and analyze models. Curve fitting using linear, quadratic, exponential, and logarithmic models are also covered.
