Hi,

I have a list of data, in the form {{0,0},{1,2},{3,3}} etc., and I would like to get the parabola that fits these points. Of course I am using the beautiful command 'Fit[]', and it is giving me a nice parabola. However, not the parabola I want!
This is because I already know the minimum point of the parabola; it is the first entry of my data list.

How do I tell Mathematica 5.0 that it has to put the minimum in the first point, and subsequently find the best fit to the other points?

If someone might deem it necessary, the complete data list:
{{-2.18879, 0.0212123},
{-0.1, 0.0243114},
{0.3, 0.0253134},
{0.9, 0.0274162},
{1.2, 0.0260532},
{2.1, 0.0279438},
{2.6, 0.0298853},
{3.3, 0.031159},
{4.1, 0.0340174},
{5.6, 0.0397283},
{6.9, 0.0477987},
{8.4, 0.0616606},
{9.2, 0.0688829},
{10.1, 0.0842424}}
