Function Graphs and Important Points
On this page we shall look at graphing function, and the key points on the graph of a function.

In this first video we see what an asymptote is and how to locate one on the graph of a function.


In this second video we look at what we mean by the term root (or zero) of a function, and how we can locate them using the graphs of functions.


Finally, we discuss what a turning point is, what is meant by a local maximum and local minimum, and once again, how to locate these important parts of a graph of a function.
