This research aims to analyse how the Instrumental Orchestration promotes that first-year students of the International Baccalaureate Diploma Programme mobilize the notion of quadratic function by executing a sequence of activities in which they use the graphing calculator. Therefore, we have decided to answer the following question: How does an Instrumental Orchestration, in which the graphing calculator is a tool, promote that first-year students of the International Baccalaureate Diploma Programme mobilize the notion of quadratic function? We use aspects of the Instrumental Genesis and the Instrumental Orchestration, as theoretical and methodological basis accordingly. The activity sequence of the research is organized in two times frames, which allowed students to make schemes of instrumented action and schemes of instrumented collective action. When carrying out the activities, the students made changes on some elements of the quadratic function to generate a transformation in its graphic representation, and based on that, they made conjectures on the horizontal and vertical translations. We also inform that students used some commands of the graphing calculator that allowed them to observe the transformations of the represented object, connect knowledges and make conjectures. Finally, through the articulation of the Instrumental Genesis and the Instrumental Orchestration, the students made conjectures on the translations of the quadratic function by making schemes of instrumented collective action, an execution mode and a didactic performance.
