Today (16 May) we celebrate Maria Gaetana Agnesi a great Italian mathematician and philosopher - she was born almost 300 years ago.
In mathematics Witch of Agnesi is a curve earlier studied and constructed by Pierre de Fermat and Guido Grandi. Agnesi in her famous summation treatise Instituzioni analitiche ad uso della gioventù italiana discussed the curve, and, after some language mixing and mistranslation, the curve has become known as the "Witch of Agnesi".

And, certainly, here is the model of the curve in Excel:
