Turning point form Reorganise x 2 + 8 x + 7 into ‘turning point form’ as follows: x 2 + 8 x + 7 = x 2 + 8 x = ( x + 4) 2 + 16 + 7 - 16 - 9 This is the equation of a parabola with its turning point at ( - 4 , - 9 ). = ( x - - 4 ) 2 - 9

Turning point form The graph of y = x 2 is transformed into the graph of y = ( x + 4) 2 - 9 by: a translation of 4 units in the negative direction of the x -axis a translation of 9 units in the negative direction
