Integrated 3 Chapter 1

Checkpoint Review: Students master different skills at different speeds. No two students learn exactly the same way at the same time. At some point you will be expected to perform certain skills accurately. Most of the Checkpoint problems incorporate skills previously developed. Each chapter has a different skill that should be mastered.

Current Concepts

• Evaluate f(x) when given x, and solve for x when given a value for f(x), as in problems 1-4, 1-5, 1-6, 1-17, 1-24, 1-25, 1-38, 1-56, and CL 1-110.
• Sketch graphs of functions and completely describe the graphs, as in problems 1-22, 1-42, 1-60, 1-83, 1-97, and CL 1-114.
• Determine domain and range given a graph, as in problems 1-35, 1-61, 1-84, 1-98, 1-107, and CL 1-111.
• Solve linear equations and/or equations with fractions, as in problems 1-9, 1-28, 1-44, 1-95, and CL 1-113.
• Solve quadratic equations, as in problems 1-19, 1-23, 1-45, 1-47, 1-87, 1-104, and CL 1-116.
• Create multiple representations of a linear relationship, as in problems 1-16, 1-39, 1-58, 1-70, 1-105, and CL 1-117.
• Creating a model of a mathematical or everyday situation, as in Lessons 1.2.1 and 1.2.2.
• Using histograms (and scatterplots) to analyze data, as in Lesson 1.2.3. (this will come back in Chapter 4 and 6)
