    Question I'm Completely Lost

    Graph the following functions:
    a. y = [x - 2]

    Except the brackets aren't just brackets. They're rather funny-looking brackets; they look something like this:
    Instead of [], they look like
    ╓ ╖
    ╙ ╜
    The brackets aren't actually separated by their tops and bottoms being on different lines, but I couldn't find any alt codes/symbols that matched the exact appearance, even in Wikipedia's Table of Mathematical Symbols. How my math teacher got it on this paper is mystifying indeed... I couldn't find it in my Algebra II book, and so I've concluded that I'm completely lost.

    Any help is appreciated. Please and thank you in advance!

    EDIT: I didn't notice the that the spacing was messed up; I've fixed it to make my meaning clearer now.

    this is known as the "floor function" and it is a kind of step function in which we round down.

    For future reference, I wouldn't advise posting a question in two different locations. TPH will get quite angry.

    Ah, floor/ceiling functions don't look that "funny"!

    Lol

    They looked funny to me because I'd never seen them before. xD!!

    Ahhh, I get it now. We didn't really study step functions; we considered them, and my textbook devotes a single paragraph to explaining them. My gratitude to you!
