Confused how?
\n" ); document.write( "The equation is already in vertex form, $\"y=a%28x-h%29%5E2%2Bk\"$ , where ( $\"h\"$ , $\"k\"$ ) is the vertex.
\n" ); document.write( "Compare to the given equation to find the vertex, ( $\"h\"$ , $\"k\"$ ).
\n" ); document.write( "The line of symmetry lies on the vertex, so $\"x=h\"$
\n" ); document.write( "Whether the parabola opens upwards or downwards is determined by the sign of $\"a\"$ .
\n" ); document.write( "If $\"a%3E0\"$ , then the vertex value is a minimum, $\"y%5Bmin%5D=k\"$
\n" ); document.write( "If $\"a%3C0\"$ , then the vertex value is a maximum, $\"y%5Bmax%5D=k\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
