i would like to derive a simple positive function from the following
Seems to me that you already have a function. Whether it is positive or not depends on the parameters you feed it.
The function Y squared will be everywhere posive in R5(5-space). I'm assuming tha small-y and big-Y are different.
Or maybe zero. It definitely won't be negative.
