Be familiar with and recognize the algebraic form for a logistic model, including the corresponding parameters and if those parameters have any meaning in the context of the functional relationship (e.g. does a parameter control the initial value, rate of change (shape), decreasing or increasing (flip), max/min, limiting values, etc.).
• Notes - Notes from this lesson.
• What is a logistic function?
• What is the difference between a finite / discrete and a continuous logistic function?
• What are the two forms of a logistic model?
• What are the parameters of a logistic model?
• What is the initial rate, initial value, and limiting value of a logistic model and how do you find them?
• What does the graph of a logistic function look like?
• How do you solve for a variable in a logistic function?
This 3-lesson miniseries on logistic functions is very similar to the exponential function miniseries. You will learn in this lesson about the parameters of a logistic model. The two forms of a logistic model (discrete and continuous) are explained as well as initial value and growth rate. This is a great introduction to logistic functions.
