Intermediate Algebra-Mathematics

Unique, enthusiastic approach, this text requires students to take an active role in studying mathematics. Focusing more on the mathematical process, students have abundant opportunities to make intuitive leaps to discover patterns — helping them develop critical thinking skills as well as mathematical confidence. Placing an emphasis on the usefulness of algebra throughout, students discover mathematical concepts while en route to solving true-to-life problems.

Most of the problems presented involve real data collected from scientific experiments and the census and require the use of a graphing calculator.
The use of the graphing utility extends from exploring concepts to verification of conjectures and pattern recognition.
Concepts are introduced graphically, numerically and symbolically.
Hands-on explorations get students to gain a solid understanding of functions, composition of functions, inverse functions using functions to model true-to-life situations and domain and range.
Emphasizes and encourages the process of discovery to come to solutions, reinforcing the concept of active learning.
Text exercises ask students to discuss mathematics and summarize their findings in writing to reinforce conceptual understanding.
Includes collaborative projects that foster teamwork among students.
Math is presented as a powerful tool reinforcing the idea that an understanding of algebra can often put an individual in a position of power to make better conjectures and predictions.
