The high school is the final phase of young people in basic education, and at this age are going through the same changes in their lives that will be huge. They live in a highly technological society and study in a school in the last century format. In this work the focus was on when addressing the issue of Quadratic Functions, seen in the first year of high school, to use technology as a motivating element of the teaching and learning process. In the lecture of this text, it is possible to see education as continuous and formative process. Pass by the history of the quadratic equation, and its resolution methods. It addressed the context of the use of technologies such as computational resource for teaching functions. It describes and demonstrates the theorems and proposals concerning the parabola, which is the graph of the quadratic function. In the last chapter the approach occurs within the dynamic geometry environment, GeoGebra. In this chapter you can check the analysis of all the points that make up the quadratic function graphic already applied to the use of the software. It was concluded among other things, the software itself will not solve all problems, but it makes the approach of the truths become more "viewable", however, it reinforces the need for confirmation of statements from expectations.
