Confused: [) Concept Question!

  1. Oct 26, 2004 #1
    I have one (hopefully) quick question for anyone out there willing to help. What's the difference between putting a pair of coordinate points, for example (3,4) in parentheses () and putting the between a bracket and a parenthesis like [3,4). Please respond soon because I need to know for homework that's due tomorrow. Thanks!

    i don't think it is a coordinate. (3,4) means 3<x<4 while [3,4) means 3[tex]\leq x<4[/tex].

    Right, not a coordinate. I think I meant to say interval. Either way, thanks very much! I just hope I can remember it now!
