Through 3 points many functions can be used. It is up to you to decide which one is the most
appropriate for you particular problem.
This seems more a question you should ask to your supervisor.
If I should guess, I would say it’s how the resolution of a calorimeter vary with the energy.
In that case the correct function is
TF1 *f= new TF1("f","TMath::Sqrt( TMath::Pow([0] ,2) + TMath::Pow([1]/TMath::Sqrt(x) ,2) + TMath::Pow([2]/x ,2) )")
Look here EM Calorimeter
