A abordagem geométrica no tratamento das funções

Abstract

This work proposes to investigate the meaning of the geometric approach for the study of the functions, and to make sure how it can contribute to the acquisition of competences in Other areas of knowledge. For that purpose, an interview was conducted with teachers from other areas of knowledge, besides the application of activities to a class of the first year of High School. From the teachers were heard reports of how the function graphs present themselves in their disciplines,the students’ ability to give you these graphs, and how you could remedy possible difficulties. Activities were applied to students Which are included in textbooks of other disciplines, namely Physics, Chemistry, Geography, Biology and Sociology, with appropriate adaptations to the study of the concepts of functions.The results lead us to emphasize the importance of the geometric approach of functions, not only in the study of Mathematics, but also in the relation of this with other disciplines.
