a is 2, b is -4 and c is 1. The parabola's vertex is (h,k). This is about to get really confusing, so hang in there with us: h is the x-coordinate of the vertex, and k is the vertex's y-coordinate.

→ Os pontos x 1 e x 2 são as chamadas raízes da parábola – os pontos nos quais a curva corta o eixo x. → O ponto C é a intersecção da parábola com o eixo y. As equações de uma ...

The graph below has a turning point (3, -2). Write down the nature of the turning point and the equation of the axis of symmetry. For the parabola \(y=(x+6)(x-4)\) determine the coordinates and ...
