Using the following Geogebra template insert three sliders, a, h, and k.
In the input field type the general form of the quadratic formula
Insert a dynamic text that displays the formula on the template
Adjust sliders until parabola approximately matches
Insert points at each pink ball
In the input screen do a regression analysis of the quadratic with fitpoly[list points separated by comas, degree of polynomial]
Because of the geometry involved in taking the photograph this is not perfect.
This template is used to show teachers how to set up sliders and dynamic formulas.
