comment Does $f:\mathbb{R}^d\to \mathbb{C}$ implies $|f|<\infty$ almost everywhere?
@REr Forget about $1/x$. That's something I come up with. I've update the post and include the text I'm confused about.

@berni-waterman I don't think anything is assumed for $f$. I'm just asking the terms and notation.

comment $Y(t)=W^2(t)\cdot e^{aW(t)}$, find $dY$
Thank you. I forgot that I can use Ito's lemma directly to check that.

comment Why $\|f-g\|=0$ if and only if $f=g$?
Thanks @Winther. But by saying almost everywhere, do we need specify the measure before the definition of this norm?

comment Is the integral finite if the integrand is $o(x^{-1})$?
Thank you @MarioCarneiro! I think the intuition is that there exist a large class of functions that converge to 0 faster than $x^{-1}$ but slower than $x^{-\alpha}$ for any $\alpha < -1$. I think I saw somewhere there's no boundary between convergence and divergence.
