The aim of this thesis is to analyze the different registers of semiotic representation, formation, treatments, and conversions in the mathematical sphere developed around the limits of functions in a university course. For the analysis of the research, we have taken as theoretical reference the Theory of Registers of Semiotic Representation (TRSR) and centered our study in the registers of algebraic representation and graph to the limit of a function. In the algebraic register we analyze the limits of functions with polynomial functions, slice functions, rational functions and graph register with continuous functions, discontinuous functions with finite jump, and functions with movable discontinuity. All of them enhance different cognitive activities as the formation and treatments of the limit of function representations in the algebraic register and graph when solving a limit of a function task. Likewise, we analyze the cognitive activities: formation, treatments and conversions from a TRSR view regarding the limit of functions in a Calculus I guided activity, within the General Studies Area of Basic Science at UNMSM. The results show that there is a prevalence of questions in the algebraic register. Different types of algebraic functions appear to enhance diverse treatments in the register with a lack of the object visualization which is an aspect of the limit of a function indicated by the graph register. Also, we can notice that there is a lack of cognitive activity of the conversion. In accordance with the TRSR, it is necessary to know more than one representation of the mathematical object as they complement each other, increase the cognitive capacity and help the understanding of the concept when the task of limits of a function is performed. The research is qualitative, we conducted a case study.
