Review: Graphing Absolute Value Functions

2

$y=a\left|x-h\right|+k$

a - slope. If a is negative, the function is reflected
(-h,k) - vertex; h is ALWAYS opposite

3

Parent Function

$y=\left|x\right|$
Slope is 1
Vertex is at (0,0)
Function opens up

4

$y=-\left|x-3\right|$

What is the slope?
What is the vertex?
Does it open up or open down?

5

$y=\left|x+3\right|-3$

What is the slope?
What is the vertex?
Does it open up or open down?

6

$y=-\left|x+6\right|-3$

What is the slope?
What is the vertex?
Does it open up or open down?
