## whadduptori 3 years ago help... please anybody?. I have the chart I'm going to post it now answers: y = 7|x + 8| –4 y = –7|x – 8| +4 y = –7|x + 8| –4 y = –7|x – 8| –4

What is the absolute value function?

I've seen this question before. You still don't understand this?

I didn't post this before, but nope!

4. micahwood50

That's weird, I'm certain I've seen this question before. Must be another guy with the same question. Anyway, do you know what parent function of absolute value looks like?

that is weird you probably have, but no I am homeschooled and do no what i am doing

6. micahwood50

Well, do you know what parent function of absolute value looks like?

nooo

8. micahwood50

You know what "parent function" is, right?

9. micahwood50

This is what parent function of absolute value look like. |dw:1349038323217:dw|

10. micahwood50

Notice that in your attachment, it opens downward, not upward. Do you know why?

i really have no idea, can you maybe explain it to me?

12. micahwood50

What don't you understand?

14. micahwood50

No, It's not a. Since function opens downward, there must be a minus sign outside the absolute value. You get it?

kinda so would it be c?

16. micahwood50

That's correct. 8 shifts the function to the left and -4 shifts it to down. Do you understand?

oh yes! no i understand!!

now
