Graphing Absolute Value Equations
How do I make one of those V graphs?

Absolute value transformationVocabulary:
Translation: shifts the parent function graph horizontally and vertically.
Reflection: it creates a mirror image of the parent-function graph across the line of reflection.

Parent Function y = │x │

Vertical Movements?
Absolute value rules: If you have minus outside the absolute value,
you move down on the coordinate plane.
y =│x│- 2
If you have addition outside the absolute value, you move up on the coordinate plane.
y =│x│+ 2

Lets practice!
y = │x│ - 4
y = │x│+ 3

Your turn!
y = │x│ + 7
y = │x│ - 2
![Page 10: Name: Date: Period: Topic: Graphing Absolute Value Equations](https://reader036.vdocuments.net/reader036/viewer/2022062723/56814027550346895dab8725/html5/thumbnails/10.jpg)
Horizontal Movements?
Absolute value special rules: If you have minus inside the absolute value,
you move to the right on the coordinate plane.
y =│x - 2 │
If you have addition inside the absolute value, you move to the left on the coordinate plane.
y =│x + 2 │

Lets Practice!
y =│x - 5│
y =│x + 6│
![Page 12: Name: Date: Period: Topic: Graphing Absolute Value Equations](https://reader036.vdocuments.net/reader036/viewer/2022062723/56814027550346895dab8725/html5/thumbnails/12.jpg)
Your Turn!
y =│x + 4│
y =│x - 1│

What about y = │x - 4 │+ 5
![Page 14: Name: Date: Period: Topic: Graphing Absolute Value Equations](https://reader036.vdocuments.net/reader036/viewer/2022062723/56814027550346895dab8725/html5/thumbnails/14.jpg)
What about y = -│x - 2 │
![Page 15: Name: Date: Period: Topic: Graphing Absolute Value Equations](https://reader036.vdocuments.net/reader036/viewer/2022062723/56814027550346895dab8725/html5/thumbnails/15.jpg)
y = -│x │
Same rule, but now it makes it look down

Verbal Comprehension Analysis
Graph the functions y = │x │ and y = │x - 3 │ together on the same coordinate plane.
What effect does the 3 have on the graph? Graph the functions y = │x │ and y = │x │- 3
on the same coordinate plane. What effect does the 3 have on the graph? Graph the functions y = │x │ and y = - │x │
together on a coordinate plane. What effect does the negative sign have on
the graph?
