The equation is already in vertex form, $\"y=a%28x-h%29%5E2%2Bk\"$ .
\n" ); document.write( "Vertex : ( $\"-2\"$ , $\"-4\"$ )
\n" ); document.write( "The vertex lies on the axis of symmetry $\"x=-2\"$ .
\n" ); document.write( "Since $\"a=-1%3C0\"$ , the value at the vertex is a maximum.
\n" ); document.write( " $\"y%5Bmax%5D=-4\"$
