Yes ok but all three of them
log(1+x)
1-exp(-x)
1/x
have that "knee". It may even be at a slight different point or I could shift them around etc but it doesnt matter. All three of them "turn around" the corner after they reach that "inflection point" for the lack of a better term. So irst they grow fast and reach that "point" and then slow down. I understand they are all different but this the pattern they follow. I was wondering what is that "inflection point". Something to do with their derivatives, the way they grow? But the derivative at the "knee" is not zero, right?
