This paper shows an excerpt of a research project that involved the analysis of the mathematical activity around the teaching of the topic "Graphing functions" in a course for future mathematics teachers in Costa Rica and Honduras. Emphasis is placed on the Mathematical Organizations (MO) present in the reference textbook used in the courses Algebra II, Introduction to Functions and Introduction to Mathematics. To carry out the analysis, use is made of the tools provided by the Anthropological Theory of Didactics (TAD). Among the main findings, we highlight that the same types of tasks were identified in both textbooks; however, there is a significant difference in the development of the techniques. As for the technologicaltheoretical block, we highlight that it is impacted by institutional conditions.
