Algebra II Elements 4.2: Graphing Inequalities in Two Variables HW: p.182-183 (24, 28, 32-42 even) Quiz 4.2, 4.6: Tuesday 11/26
Steps • Graph y = mx + b • > or < : dashed line. or : solid line. • > or : shade above the line (or to the right when vertical). < or : shade below the line (or to the left when vertical).
Algebra II Elements 4.6: Absolute Value Functions HW: p.207-208 (12, 14, 18, 22-26 even, 36, 40, 44) Quiz 4.2, 4.6: Tuesday, 11/26
4.6 Continued: Graphing Contains (0, 0) If a is positive: V-shape opens up. If a is negative: V-shape opens down. If : V-shape is narrower than If : V-shape is wider than
Determine if the graph opens up or down and if it is narrower or wider than .
Graphing Steps 1.) Plot (0, 0) 2.) Use a as a “slope” and plot additional points to the right. 3.) Using symmetry, find the matching points on the left to get a V-shape.
