I have been in trouble with the hump function(s) What are them?

Could you give me an explicit formula for "Hump"(not bump) function.

Thanks

i think any function $g(x)$ that is the derivative of a sigmoid function

$ g(x) = f'(x) $

where $f(x)$ may be any of the functions shown as examples of an S-shaped sigmoid function indicated in the Wikipedia article, any of those can be legitimately called a "hump function".

If you're referring to the category of functions called humps that I'm familiar with, then of one these functions is $f$ defined below (try plotting it for $x \in [-2, 8]$, so that $f(x) \in [0, 25]$).

$f(x) = \frac{1}{(x-3)^2+0.1} + \frac{1}{(x-2)^2+0.05} + 2$
