About Parabola

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.

What's Changed
Had to change the keyboard to alpha-numeric because some devices don't show a decimal point or negative sign otherwise. Believe me, I'm not happy about it either.
