I have some data.
data = [
(10000, 0),
(100000, 0.25),
(10000000, 0.5),
]
I want to find function(s) fitting this data. I have a possible starting point:
f(x) = Ax / (B + x) - C
Can I find A, B, C satisfying the data?
The function should be continuous. f(x) for x<=10000 does not matter but should be negligible or negative for x<=10000. The function should have an asymptotic maximum < 1.
