2.5² = 6.25 Graphs of y = x² + n can be easily drawn by moving the parabola n places up or down the y axis . y = x² + 6 - moves the parabola 6 places up the y axis ...

2. A parabola is also generated by cutting a cone parallel to the slope of the cone's sides. Because of this, parabolas are in a set of mathematical curves called conic sections.

Repare que a coordenada x do vértice V está bem no meio do segmento que une as raízes x 1 e x 2: x v é o ponto médio desse segmento. Então, o valor da coordenada x do vértice V é a média ...
