Int his lecture you will cover Special Functions. First is the Step Function which our instructor will cover as a Graph before moving to Absolute Value Functions and their Graphs. Lastly, you will learn Piecewise Functions and their Graphs before finishing with four examples.
have graphs that are a series of steps. The steps can be going
upward or downward.
are of the form f(x) = c, where c is a real number. Their graphs
are horizontal lines.
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.
