I can't find how to do it anywhere.
Stat 2 Variable application - NUM for your data, SYMB to define your columns and regression types, PLOT to see the picture.

If you are feeling adventurous, you can also do it through programming commands, or else a CAS command in the CAS environment.
You can also use the "polynomial_regression" command by specifying order 2, you find it in the catalog. It works both in home and CAS.
