1. 2.8 Absolute Value Functions

2. Create a table of values and graph.
Warm Up
Create a table of values and graph. X Y 1 2 3 4

3. The absolute value function has the
standard form of y = a|x – h| + k
Vertex: (h, k)
Symmetric about the line x = h
Opening: Up if a > Down if a < 0
The graph is wide if 0 <|a| < 1
The graph is narrow if |a| > 1

4. Example #1 Graph y = -2|x + 1| + 3 and describethe transformation.

5. Write an equation for the following graph.
y = |x-1| - 2

6. Write an equation for the following graph.
y = -3/2|x - 3|
