<span>x^2 -4x -32 </span>a =1b= -4c= -32 The x,y points of the vertex are usually referred to as Vertex = (h, k)where h = -b / (2 * a) h = --4 / (2 * 1)h = 4 / 2h = 2 k = ah^2 +bh + ck =1*4 -4*2 -32k = 4 -8 -32k = -36 vertex = (2, -36)axis of symmetry = x position = 2 Source:http://www.1728.org/quadr3.htm
