toc = X-Intercept Form = y = a(x – m)(x – n)

X-Intercepts
{x-intercepts are the points where the graph cuts through the x-axis}

Recall that to find the x-intercepts we set y = 0






 * You may have to factorise the quadratic to get the values of the x intercepts. **

Turning Point
Recall that a parabola is symmetrical on either side of the turning point. {It has a vertical axis of symmetry through the turning point}

This means that the turning point must be exactly __**half way**__ between the two x-intercepts.



You will then need to find the y-coordinate of the turning point by substituting x tp into the rule for the graph.
