Q: In search of a possibly deleted question

I'm trying to find a possibly deleted question. I don't remember the user. Is this possible? It was a question about finding $$\operatorname{E}\left[g(X)\right]$$ If my memory serves me correctly $$g(X)=\frac1{1+e^{-(X+c)}}$$ Where $c$ is a constant. Can any of the mods assist? I know for sure th...

Got it. The question is : if $X \sim N(\mu , \sigma^2)$, then find a closed form for $\mathbb E(\frac 1{1+e^{-(c+X)}})$. The only context provided is that it is not necessarily true that $\mathbb E[f(X)] = f(\mathbb E[X])$, which is quite straightforward anyway. The question is here, although it is visible only to users above a certain rep. A comment says : "by LOTUS, $\mathbb E[f(X)] = \int_{\mathbb R} f(x) \phi(x)dx$". — Sarvesh Ravichandran Iyer 2 hours ago

Side note : LOTUS, is this. — Sarvesh Ravichandran Iyer 28 mins ago

@SarveshRavichandranIyer I think that posting a copy of the question (and maybe a copy of the comment) would be a perfectly fine answer to that question. (So I'd guess you might repost some of your comments as an answer.)

In that way the question would have two answers - one about this particular question and the other one listing various methods that can be used when trying to get deleted posts.

I've sent you an invite into this rooms - so I hope you'll get some kind of notification. (I posted in chat rather in comments - the comment thread seem to me relatively long already, so I did not want to add to that even more.)

I have to admit that at the time when I started posting my answer, I have overlooked that the OP has bookmarked the answer. (It is mentioned in the question, but I have missed it on my first reading.)
