Videos and lessons to help High School students learn how to graph
functions expressed symbolically and show key features of the
graph, by hand in simple cases and using technology for more
complicated cases.

A. Graph linear and quadratic functions and show intercepts,
maxima, and minima.

- Graph quadratic functions expressed in various forms by hand.
- Use technology to model quadratic functions, when appropriate.
- Graph and find key features of piecewise-defined functions, including step functions and absolute value functions.
