2.6 Families of Functions 1.Translations 2.Stretches, Shrinks and Reflections

2
2) Stretches and Shrinks Stretching a rubber band vertically makes it longer Releasing or shrinking it makes it wider Stretching and shrinking a graph is the same idea… What does it look like?

3
2) Stretches and Shrinks Shrink Graph is SHORTER, WIDER Stretch Graph is TALLER, NARROWER

4
2) Stretches For stretches, y = a|x| a > 1

5
2) Stretches For stretches, y = a|x| a > 1 a is SLOPE

6
2) Stretches Example 1: Graph y = 2|x|.

7
2) Stretches Example 1: Graph y = 2|x|. y = 2|x| Slope = Vertex =

8
2) Stretches Example 1: Graph y = 2|x|. y = 2|x| Slope = 2 Vertex = (0, 0)

9
2) Stretches Example 1: Graph y = 2|x|. Step 1: Plot the vertex

10
2) Stretches Example 1: Graph y = 2|x|. Step 1: Plot the vertex Step 2: Use slope to plot points

11
2) Stretches Example 1: Graph y = 2|x|. Step 1: Plot the vertex Step 2: Use slope to plot points

12
2) Stretches Example 1: Graph y = 2|x|. Step 1: Plot the vertex Step 2: Use slope to plot points

13
2) Stretches Example 1: Graph y = 2|x|. Step 1: Plot the vertex Step 2: Use slope to plot points

14
2) Stretches Example 2: Write an equation for the graph below.

15
2) Stretches Example 2: Write an equation for the graph below. Vertex = Slope =

16
2) Stretches Example 2: Write an equation for the graph below. Vertex = (0, 0) Slope = 4, -4

17
2) Stretches Example 2: Write an equation for the graph below. Vertex = (0, 0) Slope = 4 y = -4|x|

18
2) Shrinks …kind of like you stepped on the graph…

19
2) Shrinks For shrinks, y = a|x| 0 < a < 1

20
2) Shrinks Example 1: Draw the graph of y = -0.5|x|.

21
2) Shrinks Example 1: Draw the graph of y = -0.5|x|. slope = 0.5 = 1 2 vertex = (0, 0) opens DOWN

22
2) Shrinks Example 1: Draw the graph of y = -0.5|x|.

23
2) Shrinks Example 1: Draw the graph of y = -0.5|x|. Slope = 1 2

24
2) Shrinks Example 1: Draw the graph of y = -0.5|x|. Slope = 1 2

25
2) Shrinks Example 1: Draw the graph of y = -0.5|x|. Slope = 1 2

26
2) Shrinks Example 2: Graph y = -0.75|x – 2| + 2

27
Example 2: Graph y = - 0.75|x – 2| + 2 slope = 0.75 shift RIGHT 2 shift UP 2 = 3 4 2) Shrinks Opens DOWN

28
2) Shrinks Example 2: Graph y = -0.75|x – 2| + 2 Vertex = (2, 2) Slope = 3 4

29
2) Shrinks Example 2: Graph y = -0.75|x – 2| + 2 Vertex = (2, 2) Slope = 3 4

30
2) Shrinks Example 2: Graph y = -0.75|x – 2| + 2 Vertex = (2, 2) Slope = 3 4

31
2) Shrinks Example 2: Graph y = -0.75|x – 2| + 2 Vertex = (2, 2) Slope = 3 4

32
Homework p.98 #17, 19, 22, 25, 34, 36, 43-45, 49 QUIZ: 2.5-2.7 Tuesday Sept 29 TEST: Chapter 2 Friday Oct 2 (I know you have a Literature test… but trust me, its better this way).
