LESSON 2.6 CONTINUED EXAMPLE 3 NAME _________________________________________________________ DATE ____________ Practice with Examples For use with pages 108–113 Graphing Linear Inequalities in Two Variables Graph y > 2x 5. SOLUTION Graph the boundary line y 2x 5. Use a dashed line because y > 2x 5. Test the point 0, 0. Because 0, 0 is a solution of the inequality, shade the half-plane above the line. y y 2x 5 1 (0, 0) 1 x Exercises for Example 3 Graph the inequality. 8. y ≥ x 2 9. y < 1 2 x 4 Chapter 2 10. y ≤ x 3 Copyright © McDougal Littell Inc.

LESSON 2.7 Practice with Examples For use with pages 114–120 NAME _________________________________________________________ DATE ____________ GOAL Represent piecewise functions VOCABULARY Piecewise functions are represented by a combination of equations, each corresponding to a part of the domain. A step function has a graph which resembles a set of stair steps. An example of a step function is the greatest integer function. This function is denoted by gx x, where for every real number x, gxis the greatest integer less than or equal to x. EXAMPLE 1 Evaluating a Piecewise Function Evaluate f xwhen (a) x 1, (b) x 1, and (c) 2x 3, if x < 0 f x 2, if 0 ≤ x < 2 x 1, if x >_ 2 x 3. Chapter 2 SOLUTION a. f x 2x 3 f 1 21 3 1 Because 1 < 0, use first equation. Substitute 1for x. b. f x 2 f 1 2 Because 0 ≤ 1 < 2, use second equation. Substitute 1 for x. c. f x x 1 f 3 3 1 2 Because 3 ≥ 2, use third equation. Substitute 3 for x. Exercises for Example 1 Evaluate the function for the given value of x. f x x 1, x 2, if x > 1 if x ≤ 1 gx 3x 2, 2x, if x < 5 if x ≥ 5 1. g5 2. f 0 3. f 3 4. g2 40 Algebra 2 Practice Workbook with Examples Copyright © McDougal Littell Inc.
