Quadratic Functions
These activities are designed for algebra students studying quadratic functions as tables, graphs, and equations.
Grades: 9th - 12th Grade
Describing Parabolas
We can extend ideas about lines (increasing, decreasing, steepness, intercepts, etc.) to describe graphs of quadratic relationships.

- Polygraph: Parabolas, Part 2
Writing Equations for Parabolas
There are different forms of the equations for parabolas. Each emphasizes something different about the parabola— either the placement of the x-intercepts or of the vertex. Deciding which form to choose is a useful math exercise.
- Match My Parabola
Playing and Modeling With Parabolas
Being able to write equations increases our mathematical power and allows us to make predictions.
