1. YoloShroom

It's either two units right, r two units left, Im on that section o math aswell XD when it's inside the parent function isn't it the opposite?

2. dancergirl45

You have four sections left is negative and down is negative while up and right are positive

3. Nnesha

$\rm f(x-h)$ here h is horizontal shift f(x) + k here k is vertical shift $\huge\rm y =\left| x-h \right|+k$ if h is negative graph will shift h unit to the right if h is positive graph will shift h unit to the left if k is positive graph shift k unit p if k is negative some unit down

4. dancergirl45

So what would be x-2

5. Nnesha

why two units right ? why not left ???

6. Nnesha

yes right. +h to the left -h to the right

If y = x-2 then the x intercept would be at x = 2 y = 0 , hence moving the graph to the right. If y = x + 2 , the x intercept would be at x = -2 , y = 0 , therefore moving to the left. You can graph it out to see the difference. c:

8. Nnesha

why do you think its A ??

9. Nnesha

if h is positive then graph shift to the left side if h is negative then graph shifts to the right side

@vera_ewing But h is minus in this case?

11. Nnesha

right. one unit to the right side

12. Nnesha

it's 2** not one

13. Nnesha

which one do you think ? you just said it or was it a educated guess ?

14. Nnesha

i didn't say it's not A ,B C or D :=) according the information which one do you think it's ? i repeat if he is negative then graph shift to the right side if it's positive then graph shift to the left side |dw:1444244253550:dw|

15. Nnesha

there isn't any number outside the bar so pretty obvious it can't go up or down :=)

16. vera_ewing

Well I think it's A!! Is that correct?

17. Nnesha

why do you think it's A please explain :=)

18. vera_ewing

Because +h has to go to the left!

19. Nnesha

but it's $y = \left| x\color{Red}{-} 2 \right|$

20. Nnesha

focus on the sign between x and a number

21. vera_ewing

Ohh so it's negative! That means it goes to the right, so it is C!

22. Nnesha

|dw:1444244481009:dw|

23. Nnesha

yes right

24. vera_ewing

Ok thanks!
