Lesson 2.1 Graphing Absolute Value Functions
Absolute Value The distance from zero Will always be positive
Graphing Absolute Value through transformations
Graphing Absolute Value through transformations
Steps for graphing absolute through transformation Identify and graph the vertex (remember the vertex is (h,k) and h is always opposite sign) Use the a and a table to find and graph two more points one on each side of the vertex X f(x) af(x) X represents the distance to move over from the vertex I always use one F(x) will be the parent function IxI how much we move up and down if there is no a af(x) will be the parent function IxI times a (the stretch or compression) how much we move up or down if there is an a in the equation
Example Graph y=Ix +3I
Example Graph y=IxI - 5
Example Graph y=2IxI
Example Graph y=1/2Ix +3I - 2
Example Graph y= -3Ix 2I +4
You Try Graph y=2Ix + 1I 1
Graph to equation What is the equation of this graph
