App Description

Would you like to ace your next test on quadratic functions?

"Parabola" tells you everything you ever needed to know about parabolas but were afraid to ask.

Enter a quadratic function in standard, vertex, or intercept form, and this application instantly displays:

- The orientation of the parabola
- The coordinates of the vertex
- The axis of symmetry
- The coordinates of the focus
- The equation of the directrix
- The x-intercepts
- The y-intercept

Since it's crucial for students to understand the concepts behind the formulas, "Parabola" includes a thorough explanation of the computations that are performed.

Students and teachers will find this application to be indispensable.
