Home > Intermediate 2 > {$page}

Overview
In this outcome you have to:
 * determine the equations of quadratic functions of the form y = (x + a) 2 + b and y = kx 2 from their graphs
 * identify the nature and co-ordinates of the turning point and the equation of the axis of symmetry of a quadratic of the form y = k(x + a) 2 + b where k = ± 1
 * solve quadratic equations graphically, by factorisation and by using the quadratic formula
