This lesson picks up from where the basic introduction lesson left off and the first two parabolas graphed are the same that were graphed in the introduction. There are two more parabolas graphed in this video too. For more advanced graphing, go on to the next lesson in this series. Also, all of these parabolas are drawn on the same axes so you can see what adding or subtracting values from the function do to the graph.
