Graph Transformations

Write an absolute value function given the following transformations:
Reflection across the x-axis
Vertical shift right 2 units
Horizontal shift down 7 units

• y = -|x + 2| - 7 
• y = |x - 2| - 7 
• y = -|x - 2| - 7
• y = -|x - 2| + 7

Describe the transformation:

• f(x +3)
• f(x-3)
• f(x) - 3
• f(x) + 3 

What transformation occurred?

• f(x+4)
• f(x) + 4
• f(x-4)
• f(x) -4

Describe the parent graph transformation

• h. stretch, left 1, down 3
• h. shrink, right 1, down 3
• v. shrink, left 1, down 3
• v. stretch, right 1, down 3

Describe the transformation from the parent graph.

• h. stretch by factor of 2, left 5
• h. shrink by factor of 2, up 5
• v. stretch by factor of 2, down 5
• v. shrink by factor of 2 right 5

• A.
• B.
• C.
• D.

• y = Ix + 2I - 1
• y = -Ix + 2I - 1
• y = -Ix - 2I - 1

The blue graphs is the parent function f(x)=|x|, the red must be

• g(x)=|x+2|
• g(x)=|x|+2
• g(x)=|x-2|
