$\"y+=+-2x%5E2-8x-5\"$
\n" ); document.write( " $\"y+=+-2%28x%5E2+%2B+4x%29-5\"$
\n" ); document.write( " $\"y+=+-2%28x%5E2+%2B+4x%2B4%29-5%2B8\"$
\n" ); document.write( " $\"y=-2%28x%2B2%29%5E2%2B3\"$
\n" ); document.write( "The vertex of the parabola is (-2,3).
\n" ); document.write( "The axis of symmetry is $\"x=-2\"$ .
\n" ); document.write( "The domain is unlimited: ( $\"-infinity\"$ , $\"infinity\"$ ).
\n" ); document.write( "Since the coefficient for $\"x%5E2\"$ is negative, the parabola opens downward, and the vertex is the maximum value.
\n" ); document.write( "The range is ( $\"-infinity\"$ , $\"3\"$ ).
