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 ...

we can see that this parabola has 2 roots, diagram B has 1 root and diagram C has no roots. What type of roots the equation has can be shown by the discriminant. The discriminant for a quadratic ...
