Overview

Are you looking for a new sound in algebra? Seeking to answer the perennial question “But what is this good for?” Elementary & Intermediate Algebra models authentic data through curve-fitting to give new meaning to the math. It uses authentic, real-life data sets to find models and derive equations that fit the scenario. The curve-fitting approach teaches the mathematical concepts within the context of data, engaging you from the start and building conceptual understanding. The 3rd Edition updates data sets throughout and offers new Large Data Set exercises to get you comfortable with analyzing big data. New downloadable data sets support the appropriate use of technology when completing exercises and labs. Throughout, even more resources are provided for you to practice, review and explore concepts.
