Subject: Re: Curve fitting to data

A quadratic indeed fits this function very well.  The
zunzun.com function finder was run with the option
to try every possible function, rather than limit
to simple curves only.  This can be done on the site
in two ways:

1) Use the function finder "Smoothness Control" to
only allow functions with a few coefficients

2) Use the function finder "Equation Family Inclusion"
and disallow the polyfunctionals - these generate
many thousands of basically random functions to test.
