Homework Help: Asymptote trouble

  1. Apr 17, 2008 #1
    scatter plot needs a regression? or line best fitting it.

    so far y=3/((x-3.75)/2.75)+9 is a pretty good fit

    graph is attached

    any suggestions on how to get rid of everything left of the asymptote?

    Hello, I do not know how your calculator works. But if you set the minimum value of x so that the bottom left curve won't be displayed, it should work. Or are you looking for another equation to fit your data?

    A few comments:

    The 3 and 2.75 in your equation can be combined into a single number.

    As kazumi said, changing the range of x-values should get rid of the unwanted curve. Looks like x_low = 3 should work here.

    If you're looking to improve the fit, it can be done in Excel. You would need to have the Solver add-in installed.
