2. Warm – up #6 Solutions

4. Lesson 2-7 Absolute Value Graphs Day 1 Algebra II

5. Learning Objective To graph absolute value functions

7. Graphing Absolute Value Functions Find the vertex Make a table, go two numbers above and below the x-value of the vertex. Plug in to find y-value The y-values SHOULD reflect over the vertex if you found the vertex correctly DO NOT ASSUME you have the correct vertex

8. Vertex: (0, 0) Axis of Sym: x = 0 x y V(0 0) -2 1 2 2 1 1 2

9. Vertex: (0, 0) Axis of Sym: x = 0 x y V(0 0) -2 1 2 4 2 2 4

10. Vertex: (0, 0) Axis of Sym: x = 0 x y V(0 0) -2 1 2 1 0.5 1

11. Vertex: (0, 0) Axis of Sym: x = 0 x y V(0 0) -2 1 2 -2 -2

12. Vertex: (0, -4) Axis of Sym: x = 0 x y V(0 -4) -2 1 2 -2 -3 -2

13. Vertex: (3, 0) Axis of Sym: x = 3 x y V(3 0) 1 2 4 5 2 1 1 2

14. Vertex: (-2, 3) Axis of Sym: x = -2 x y V(-2 3) -4 -3 0 5 4 4 5

15. Vertex: (-2, 3) Axis of Sym: x = -2 x y V(-2 3) -4 -3 0 1 2 2 1
