4 2.8: Absolute Value Functions Goals Represent Absolute Value Functions With simple transformations Using Absolute Values in Real Life 4

5 Recall: Absolute Value Graph the piecewise function: f(x) = x 5

6 Graph Experiments 1. Graph f(x) = a x for a=1 a=-1 a=3 a=-3 a=1/3 Where is the vertex? What does the value a do to the graph? 6

7 Graph Experiments 2. Graph f(x) = x-h for h=1 h=-1 h=3 h=-3 h=1/3 Where is the vertex? What does the value h, inside the absolute values, do to the graph? 7

8 Graph Experiments 2. Graph f(x) = x - k for k=1 k=-1 k=3 k=-3 k=1/3 Where is the vertex? What does the value k, outside the absolute values, do to the graph? 8

9 Graphing Absolute Value The graph of f(x) = a x-h +k Vertex (h,k) Symmetric in the line x=h V-shaped Opens up if a>0 Opens down if a<0 Opens or Closes Wider than y= x if a <1 Narrower than y= x if a >1 Plot: Graph the vertex, then one point, use symmetry 9
