- This paper seeks to demonstrate a particular property of the quadratic function. It describes the influence of each of the expression coefficients in y=ax^2+bx+c,with a,b,c ∈R and a ≠0 regarding the graph of the parable and, in particular, analysing the influence of the coefficient b, detailing the behavior of the vertex of any quadratic function according to the variation of b. We conclude that the vertex variation draws another quadratic function in which the resulting parable has concavity in the opposite direction and symmetry to the y axes.
