What about y = -│x - 2 │

Slide 15

y = -│x │

Same rule, but now it makes it look down

Reflection of the

Parent-function

Slide 16

Practice Time!!! Algebra Aerobics!

1) y = │x - 1│

2) y = │x +3│

3) y = │x │ + 5

4) y = │x│ - 4

5) y = │x + 3│ + 3

6) y = │x - 1│+ 2

7) y = -│x - 6│

8) y = -│x │- 4

9) │x│+ y = - 3

10) y = -│x + 1│ - 1

Slide 17

Mix Algebra Aerobics

y = │x - 4│

y = │x + 5│

y = │x │ + 3

y = -│x + 2│ - 2

y = -│x - 7│ + 8

4x + 3y ≤ 24

y ≥ 6

x ≥ 4

y ≥ -3x -1
