Videos and lessons to help High School students learn how to write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function.

A. Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.

- Factor quadratics and complete the square (with II.2.A.SSE.3) to find intercepts, extreme values, and symmetry of the graph.
- Transition between different forms of quadratic functions and identify the advantages of each.
