TF1 and Function Zeroes

ROOT
1

This seems like an awfully silly question but I haven’t been able to find it in the documentation anywhere. Is there any method to find the zero for a TF1 function? I checked the TGraph and TF1 classes, and I was not able to find anything.

Thanks in advance for any help,

Use TF1::GetX. See:
root.cern.ch/root/htmldoc/src/TF … l#TF1:GetX
