Radical Radical Functions Functions • How do we graph radical functions and inequalities? • How do we transform radical functions by changing parameters? HoltMcDougal Algebra 2Algebra 2 Holt Radical Functions In addition to graphing radical functions, you can also graph radical inequalities. Use the same procedure you used for graphing linear and quadratic inequalities. Holt McDougal Algebra 2 Radical Functions Graphing Radical Inequalities Graph the radical inequality. 1. y 2 x 3 3 Vertical shift: 3 units down Greater than: shaded above curve Holt McDougal Algebra 2 Dotted curve 2 times as fast Radical Functions Graphing Radical Inequalities Graph the radical inequality. 2. y x 1 2 3 Horizontal shift: 1 unit to the left Vertical shift: 2 units up Less than: shaded below curve Holt McDougal Algebra 2 Solid curve opposite and normal Radical Functions Graphing Radical Inequalities Graph the radical inequality. 3. y 2 x 1 3 Horizontal shift: 1 unit to the right Vertical shift: 3 units down Less than: shaded below curve Holt McDougal Algebra 2 Dotted curve 2 times as fast Radical Functions Graphing Radical Inequalities Graph the radical inequality. 4. y 2 x 2 Vertical shift: 2 units up Holt McDougal Algebra 2 Solid curve Left 2 times as fast Radical Functions Graphing Radical Inequalities Graph the radical inequality. 5. y 2 x 2 1 3 Horizontal shift: 2 units to the right Vertical shift: 1 unit up Less than: shaded below curve Holt McDougal Algebra 2 Solid curve opposite 2 times as fast Radical Functions Graphing Radical Inequalities Graph the radical inequality. 6 . y 2 x 2 1 Horizontal shift: 2 units to the left Vertical shift: 1 unit up Less than: shaded below curve Holt McDougal Algebra 2 Dotted curve opposite 2 times as fast Radical Functions Lesson 7.1 Practice B Holt McDougal Algebra 2
