    It should be noted that you do not require calculus to find the turning point of a quadratic.
    Another method is to use the fact that the curve is symmetical. The x co-ordinate of the turning will be mid-point of the two positions where the curve crossses the x axis ( although not all curves cross the x axis) . Substitute x into the equation to get y.
