Hello MHB,
I am reading about a rule which I got no clue what it's name is on english but I think that you Will understand.

My question is what do they mean with that \(\displaystyle D_g\) and \(\displaystyle D_f\)

Regards,
\(\displaystyle |\pi\rangle\)

Looks like $D_g$ means the domain of g.
That is the set of all values of x for which g(x) is defined.
