# Math : Lowering function

(Amir Habibi) #1

Couldn’t find Math category :))
Need a mathematical function (X) when given 0 the output will be 1 , 50 the output will be 0.25 , …
0 (X) = 1.0
50 (X) = 0.25
100 (X) = 0.15
and so on …

Try this:
f(x) = (1+x/-W)^a;

It comes from the equation of a line parameterized to have the points at 0,1 and W,0 and power to ‘a’ to find the exponential decay you need.
