Types of Growth Functions

The video tutorial explores different types of growth functions, including linear, logarithmic, polynomial, exponential, and factorial growth. It begins with an introduction to growth functions and their relevance to the binomial theorem. The teacher explains linear growth as a steady increase, logarithmic growth as a slowing curve, polynomial growth as a family of functions with increasing powers, exponential growth as a rapid increase, and factorial growth as an astronomical rise. Each type of growth is illustrated with examples and comparisons to help students understand their characteristics and differences.
