Resumen de An alternative to representing the quadratic function with GeoGebra

Agustín Carrillo de Albornoz Torres

• Following the line of previous works, this article proposes an alternative to the traditional classroom activities, especially in Secondary Education and Baccalaureate, aimed at the study and representation of the quadratic function. The usual approach is to propose an activity in which the expression of the functions is given as data to carry out the necessary calculations for its representation or to determine some values when this fuction appears in a context problem. The alternative porposed here seeks the opposite process, using the posibilites offered by GeoGebra, so that given some points that belong to the function, the aim is to represent it in order to obtain its quation, which will be given by the programme itseflf.
