Answer 1

what u think?

Answer 2

I think it's C Or D.

Answer 3

Round to nearest 10. So, for instance, 14 should go to 10, but 16 should go to 20. Which graph represents that sort of rounding?

Answer 4

A? Sorry, i'm really dumb with math.

Answer 5

yes queelius is explaining right

Answer 6

Graph A cannot be it. For instance, if you choose x = 14, you get y = 20.

Answer 7

D?

Answer 8

That is, on graph A you get that.

Answer 9

On D, if you choose x = 25, you get y = 10. That can't be it.

Answer 10

Sorry, ><

Answer 11

It's gotta be B, because when I was looking at A, it looks kinda identical.

Answer 12

Then again C looks like it could be too, gah.

Answer 13

I;m going to go with C.

Answer 14

Go over the entire range of one of those horizontal lines on part B and see if it makes sense. On graph B, if you go to x = 16, which y value do you get?

Answer 15

y=20 right?

Answer 16

Yes. What if you let x = 14, which y value do you get?

Answer 17

10?

Answer 18

Yes. You see that, when you plug in an x value, you get the expected y value -- the "round to the nearest ten".

Answer 19

Therefore, it is graph B. It can't be C because if you plug in an x = 10, you get a y = 0.

Answer 20

Thank yo so much that makes sense to me.

Answer 21

Im gonna post a new question mind if I tag you for help ?

Answer 22

I'm glad the graphs make more sense to you now.
