For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of the axis of symmetry. The roots are \(x=-6\) and \(x=4\). The aixs of the symmetry is ...

Find the equation of the line of symmetry and the coordinates ... so the graph will cross the \(y\)-axis at (0, -3) Writing \(y = x^2 – 2x – 3\) in completed square form gives \(y = (x ...
