Transformations of Quadratic Functions

Using interactives, participants observe how changing symbolic expressions alters their graphic representation, and vice versa. By working with families of quadratic functions, they deepen their understanding of the role of each symbolic form in gleaning information about a function.

Professional Development Goals

• Represent, categorize and use families of quadratic functions in multiple formats
• Understand how each of the three major symbolic forms — polynomial, root (product), and vertex — serve a different purpose and how each relates to graphic transformations
• Exploit function notation as a useful tool to visualize the relationships among related quadratic functions
