Summit Math Algebra 2 Book 7: Exponential Functions

This textbook series supports both independent study and classroom learning, empowering students to learn at their own pace, whether working individually or collaboratively. The author makes each concept easy to understand and actively engages students in a step-by-step process of building genuine understanding, rather than memorizing formulas without knowing why they work. With careful pacing, clear explanations, and a detailed answer key for timely feedback and helpful guidance, the uniquely scaffolded approach allows students to learn math anywhere, at school or at home.

Written by a teacher with over 20 years of experience, each feature is designed to benefit students. Published as separate books instead of a single textbook, students feel a sense of achievement when they finish each book, making learning feel less intimidating. Each lightweight book has 2 parts. The first half uses small steps to guide students through the process of constructing each concept, while the second half provides additional practice to reinforce learning and improve retention. Every section includes an answer key to provide teacher-like feedback that helps students keep moving forward. This curriculum is named Summit Math to reflect the author's belief that learning is like hiking. Anyone can reach the summit, at their own pace, if they keep taking small steps.

Book description:
In this book, students learn that exponential patterns come from repeated multiplication. They also learn that exponential patterns can be viewed as repeated percentage changes. They investigate scenarios that involve both exponential growth and decay. They learn how to graph exponential functions. They also learn how to use systems of equations to find the equation for an exponential function when they know 2 points. This book builds on Algebra 1: Book 1 and Algebra 2: Book 6.
