In the Special Functions lecture, you will learn how to determine and use step functions, absolute value functions, and piecewise functions. Comprehensive examples follow each special function as well as four additional examples at the end to test your grasp of the new concepts.
Step functions have graphs that are a series of steps. The steps can be going upward or downward.
Constant functions are of the form f(x) = c, where c is a real number. Their graphs are horizontal lines.
A piecewise function is defined differently on different intervals in the domain. The graph consists of a different graph on each interval
The absolute value function is an example of a piecewise function. Its graph looks like a V, translated horizontally or vertically.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
