Função Quadrática: Caracterização e Aplicações

Abstract

In this work, we study quadratic functions as well as their characterization, representing graphic representation and applications of the parable. In the development of the work, an attempt was made to

contemplate the algebraic form of the quadratic function through the deduction of its equation, addressing some demonstrations not found in high school textbooks. Regarding the graphical representation we demonstrate that the graph of the quadratic function is a parabola

and as an application we justify why mirrors and antennas are parabolic. present we also have the relationship between quadratic function and arithmetic progressions a

from the Quadratic Functions Characterization Theorem and use the Jump game of Rã to motivate students and teachers to study this Theorem.
