I have a question, and I really need your help, because I think I'm not understanding the reason...

I have a potential model..

F[x_] := k x^n

for the next graphic...

enter image description here

the fits shows a error and it doens't draw the curve completly...

NonlinearModelFit::sszero: The step size in the search has become less than the tolerance prescribed by the PrecisionGoal option, but the gradient is larger than the tolerance specified by the AccuracyGoal option. There is a possibility that the method has stalled at a point that is not a local minimum.

data2={{0.000205, 81.41}, {0.000422, 58.14}, {0.00144, 30.51}, {0.00198,25.93}, {0.00396, 18.98}, {0.00485, 16.83}}

and and I used this...

FindFit[data2, F[x], {k, n}, x]

Why does not mathdoesn't Mathematica completely draw the Fitfit?
