I need an equation for some data points. My data points are (97.57,6.14), (90.54,7.03), (81.99,8.55), (71.47,10.52), (56.5,14.97)
and (31.88,24.62).  I'm trying to find the nonlinear equation that describes these points, but I'm having trouble.  Can anyone come up with it.
It's pretty much impossible to come up with "the" nonlinear equation that describes the data without more information on the problem, such as the source of the data and the desired fitted form, or at the very least the units.  What's the independent and dependent variables?  Time?  Position?  Elevation? Force? Voltage? Money?  You can't just list random data points and expect to automatically fit the "correct" function to it; we need more information to solve this problem.
