Complete the square to convert to vertex form.
\n" ); document.write( " $\"y=%28x%5E2%2B6x%2B9%29%2B7-9\"$
\n" ); document.write( " $\"y=%28x%2B3%29%5E2-2\"$
\n" ); document.write( "So the minimum value occurs at the vertex so,
\n" ); document.write( " $\"y%3E=-2\"$ or [ $\"2\"$ , $\"infinity\"$ )
\n" ); document.write( "and the domain is all real numbers ( $\"-infinity\"$ , $\"infinity\"$ )
