2. Vocabulary absolute value function: _________ Ex: x y
Vertex: highest or ______
point
Axis of Symmetry: ______

4 Major Types:
Translation
Reflection
Width (narrower, wider, stay the same)
Rotation

Vertex: ____
AOS: ____
Absolute Transformation in Vertex Form:

5. We Will Only Deal With…
VS.

6. Vertex

Use (+/-) slope to plot points
Connect and make that “V”!
Compare with y = |x|
Zeros:
