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
As if that's not enough, this application converts quadratic functions between standard, vertex, and intercept form automatically.
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.
