The research app for quadratic functions, interrelations between term and graph of a quadratic function can be analyzed independently.

In the left half of the two-part app can be the appearance and change location of the standard parabola (dashed) and simultaneously observe the effects on the parameters of the parabolic equation in the right half of the app. Conversely, in the right half of the app change the parameters of the parabolic equation and simultaneously observe the effects on the function graph in the left half of the app. In both cases the deformed parabolic equation, the value of the discriminant and possibly the zero point (s) of the corresponding function are displayed in the lower half of the app.
