Here's the question you clicked on:

How would you graph [6,14]?
If you are only graphing it with no other equations, you would just go over 6 ( the x-coordinate) and up 14 the (y-coordinate)
I don't know what you are saying, sorry.
*[6,14] being a interval notation.
oh ok. I thought they were just parenthesis sorry:) Is that the number line that that you put a closed or open dot on and the arrow pointing a certain way?
would the graph be going left or right and would it be opened or closed circle?

I have only seen it 6<x<14...
when you have [: closed circle on the left, ]: closed circle on the right If you had like (6,14) then it means open circle on the left, open circle on the right If you had lik (6,14]: open right on the left, closed circle on the right Your book might use ]6,14[ instead of (6,14) as notation (but I have rarely seen this)
That is interesting I have never seen it done like that. With the parenthesis representing closed or open circles and all..
If you had like (6,14]: open circle on the left, closed circle on the right***
Oh it's actually really common notation. What year are you in @Emah ?
@kirbykirby what grade/year are you in?
Hmm ok. Well maybe it differs where you're from. We saw this notation by then. But oh well if you take more math courses you will surely see this notation. Probably in calceulus... and definitely in university math courses :)
I'm a second year math major in university
Yeah I have only seen it the way I said before. It's the same end result, just a different way of getting it. Have you seen it 6<x<14? @kirbykirby
Ah okay. Yeah, this stuff is in University. I don't think high schools in my country have any textbooks/teachers teaching students this way.
Hm interesting. My teacher introduced intervals this way in our grade 9 o.o But yeah I suppose it depends where you're from lol. Yes @Emah, you see this way as well and it's also very common :)
Although it would be more specifically be \[6\le14\]
Our country's on decline when it comes to the educational standard of mathematics. I'm in Australia. We're now at rank 20th+ when it comes to maths standard.
oops \[6\le x \le14\]**
Well it's really just notation, it's not that big of a deal :)
So is mine.. haha i'm from America. That's super cool that your from Australia, I have always wanted to go there:P
K this kid is probably getting annoyed so I'm gonna go...
Go to Australia with Ellen. I heard she's taking a select group to Australia for free.
