Homework Help: Graphing 1/x

  1. Aug 26, 2011 #1
    1. The problem statement, all variables and given/known data
    What is an easier way to graph 1/x? How I am currently doing it is in the "The attempt as a solution" section.

    2. Relevant equations

    3. The attempt at a solution
    The current way I graph some hyperbola like the one mentioned is by first finding the asymptotes. Then, I plug in some x-values and find out where, relative to the asymptotes, the points lie which will show where the curves are. Basically, my method involves plugging and chugging x-values which will show where the curves are on the coordinate plane. I was hoping there was an easier way to do this.

    Use a graphing calculator.... this is one of those graphs you just memorize

    I have one of those. I just don't like remembering things for the sake of remembering :S

    you could just think about what happens when x gets very small or x gets very large. So check
    x[itex]\rightarrow[/itex] infinity
    x [itex]\rightarrow[/itex] 0-
    x[itex]\rightarrow[/itex] negative inifinity

    That's kind of how I was doing it. I guess that's the only real way to get it done lol. Thank you :smile:
