    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)

    *[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?

    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..

    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 :)

    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.
