To the Student You are about to embark on an exciting journey. In this course, you will learn not only more about algebra but also how to apply algebra to describe and make predictions about authentic situations. This text contains data that describe hundreds of situations. Most of the data have been collected from recent newspapers and Internet postings, so the information is current and of interest to the general public. I hope that includes you. Working with authentic data will make mathematics more meaningful. While working with data about authentic situations, you will learn the meaning of mathematical concepts. As a result, the concepts will be easier to learn, because they will be connected to familiar contexts. And you will see that almost any situation can be viewed mathematically. That vision will help you understand the situation and make estimates and/or predictions. Many of the problems you will explore in this course involve data collected in a scientific experiment, survey, or census. The practical way to deal with such data sets is to use technology. So, a graphing calculator or computer system is required. Hands-on explorations are rewarding and fun. This text contains explorations with step-by-step instructions that will lead you to discover concepts, rather than hear or read about them. Because discovering a concept is exciting, it is more likely to leave a lasting impression on you. Also, as you progress through the explorations, your ability to make intuitive leaps will improve, as will your confidence in doing mathematics. Over the years, students have remarked to me time and time again that they never dreamed that learning math could be so much fun. Jay has a wide variety of interests.
