Sshaped


Jshaped


Wshaped


Ushaped

Detailed explanation1: A logistic growth curve is an Sshaped (sigmoidal) curve that can be used to model functions that increase gradually at first, more rapidly in the middle growth period, and slowly at the end, leveling off at a maximum value after some period of time.
Detailed explanation2: A graph of logistic growth is shaped like an S. Early in time, if the population is small, then the growth rate will increase. When the population approaches carrying capacity, its growth rate will start to slow. Finally, at carrying capacity, the population will no longer increase in size over time.
Detailed explanation3: The logistic function shows an initial exponential growth until the inflection point, and an exponential decay from then on until reaching the upper asymptote (i.e. exhausting the stock). Hence the typical Sshaped pattern which gave the curve its popular name.
