The coordinates of the turning point and the equation of the line of symmetry can be found by writing ... 3)\) and so the graph will cross the \(x\)-axis at \(x = -1\) and \(x = 3\).

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 ...
