    The study of functions has several applications in daily life and in several areas of knowledge. When you analyze the time and wear that you have when sketching the graph of a function we ask a simple question: "Is there another way to this sketch?". In this perspective, this work proposes to analyze the application of the use of graphical environments (in particular GeoGebra) in the study of graphs of functions and their properties. In order to do so, some activities were proposed in order to investigate the use of the software and its contribution to the conjectures of problem solutions. The research field is a private school located in the municipality of Paracatu-MG. The activities were developed in two groups composed of 15 students each, from the 3rd year of high school, of the referred institution número A questionnaire denoted by "Final Questionnaire" and two evaluations called "Diagnostic Evaluation 1" and "Diagnostic Assessment 2" were applied with the purpose of evaluating the student's perception difference at the beginning and end of the project. It was expected that in the course of the work students would be encouraged to study math more dynamically. The results found point to the importance of using methodologies and tools that are capable of motivating the student in the learning process. By becoming a subject of learning the student can understand the context studied and draw their own conclusions by associating the lived with what is taught by the teacher.
