    uh... it's a function?

    its limit is 1 when x->infinity
    it is not defined when x=0

    yeah like christian stated

    I graphed it use Graphmatica, give that a search in google and its free.

    You don't need to call it anything Sophia, just tell the students f(x)=x+1/x. That's all. And just incase you wanted some helpful info on actually graphing it, its an odd function so theres antisymmetry. and www.calc101.com has a graphing program on it, that might help as well.
