Equation and graph

one of infinitely many things. if you have a set of choices, it could be possible to narrow it down to a "best" option.
see: arctan(x-3)+4 or (x-5)/sqrt((x-5)^2+1)+4 or e^((x-3)/(|x-3|+1)), etc
see: arctan(x-3)+4 or (x-5)/sqrt((x-5)^2+1)+4 or e^((x-3)/(|x-3|+1)), etc
If I have a graph like this (see attachment), what the equation will be?
It looks like a logistics curve.
Many examples:

For example, the horizontal axis could be associated with the number, n, of people from 1 to 365,
and the vertical axis could be associated with the probability that among n randomly chosen people,
that at least two people would share the same (unspecified) birthday.
Hello, xykhzz!
. . where \(\displaystyle (h,k)\) is its inflection point.
I see a "horizontal" cubic: .\(\displaystyle x-h \:=\: (y-k)^3\)If I have a graph like this (see attachment), what the equation will be?
. . where \(\displaystyle (h,k)\) is its inflection point.
It helps a lot.
Thank you so much!
