A Função do 2º Grau
Paulo Pereira (Equaciona)
Compositor: Paulo Pereira
A função do 2º grau
É fácil de reconhecer
A lei, a lei de formação
É AX²+BX+C
Se o A é maior que zero
A concavidade fica pra cima
Se o A é menor que zero
A concavidade fica pra baixo
-B/2A, -Δ/4A
São as coordenadas do vértice da parábola
-B/2A, -Δ/4A
São as coordenadas do vértice da parábola
A intersecção com o eixo x são as raízes
A intersecção com o eixo y é o ponto (0, C)
A intersecção com o eixo x são as raízes
A intersecção com o eixo y é o ponto (0, C)
-B/2A, -Δ/4A
São as coordenadas do vértice da parábola
-B/2A, -Δ/4A
São as coordenadas do vértice da parábola
