I'm trying to find a function that i could fit to only a few datapoints
x = [10 50 90 100]
y= [0.77 0.75 0.55 0.51]
I have troubles finding a function with only one or two free parameters to fit.
I got stuck with something like:
y(x)= 1 - exp(k*x)
What do you guys think? What would be the best function?
Thanks in advance!!
