Linear Absolute Value Functions:

y=x

x	y
-2	-2
-1	-1
0	0
1	1
2	2

 

y=|x|

x	y
-2	2
-1	1
0	0
1	1
2	2

 

Critical point/point of inflection: where the graph changes direction

y=-4x+6

y+|-4x+6|

ALL THE Y VALUES MUST BE POSITIVE SO THE GRAPH LET GO TO 0 THEN BOUNCE UP.

Quadratic Absolute Value Functions:
