The present study aims to analyze the coordination between Records of Semiotic Representation when the notion of Quadratic Function is mobilized in the development of a sequence of activities with students of the Humanities careers. The research was carried out with students of the first cycle of the Humanities careers of a private university in Peru, whose ages fluctuate between 15 and 17 years. The statement of the study problem is based on the research background that allows exploring the difficulties faced by higher education students when they mobilize the notion Quadratic Function in relation to the abuse of numerical treatments, which leads to leaving aside the visualization of the object mathematics in the graphic register (visual variables that indicate characteristics of the represented object) and their relationship with its representation in the algebraic register (parameters of the quadratic equation) of the Quadratic Function. For the present research, we take the Semiotic Representation Registers theory developed by Duval (1988) as a theoretical framework and, as a methodological reference, we take aspects of the qualitative methodology of Fox (1981). Regarding the experimentation and analysis phase, we adapted a didactic sequence developed in Rodríguez's research (2018) and applied it in two moments, the purpose of which was to promote the visualization, according to Duval, of the representation of the mathematical object in the graphic register. The results obtained allowed to show that, in a higher percentage of the activities developed by the students, it was possible to establish the visualization of the Quadratic Function in the graphic register by means of the identification of the visual variables and the correspondence of the values of these visual variables with the significant units of the representation of the mathematical object in the algebraic register, so this discrimination of the visual variables and the significant units was carried out through qualitative recognition, as suggested by Duval (1999), and that through this Qualitative recognition, through the way of global interpretation (third way of treatment of graphic representations), it was possible to define the relevant visual variables for graphic interpretation.
