Resumo
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.
