Perfect Squares are produced by squaring a single term. This can be either a number or an expression. When it is an expression we end up with a type of quadratic of the form:

or

This activity explores the properties of this family of functions and their graphs, known as parabolas.

The unit includes an AMSI Interactive online module, a range of other AMSI Schools and external links and video tutorials and some extension or enrichment ideas to take their understanding further. A short quiz at the end of the AMSI Interactive will help students to test their understanding at the completion of the unit.
