→ 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 ...

Solve the quadratic equation \({x^2} - 6x + 8\) by completing the table below, plotting the points and drawing the parabola then reading off the roots from the graph.
