Its "generalized" form is also known as the Richards function, and its derivative is the Hubbert curve. It is useful in Rasch modeling, in which the subject's ability to answer and the question's difficulty are equal at a point where the probability of a correct answer is one-half, while it's also used as an activation functions in neural nets.

Functions of this form are relevant to autocatalytic reactions, where the product catalyzes its own formation, and it was first described by Verhulst in response to statements by Malthus. For 10 points, give the term for this function, such as e to the x over quantity one plus e to the x, the most common example of a sigmoid curve, typically applied to problems of population growth.
