The vertex of the quadratic function $\"y+=+a%28x-h%29%5E2+%2B+k+\"$ is (h,k).
\n" ); document.write( "The line of symmetry is $\"x+=+h\"$ and the maximum or minimum value is k.
\n" ); document.write( "Therefore, in $\"f%28x%29+=+-%28x%2B1%29%5E2-9\"$ , the vertex is (-1,-9).
\n" ); document.write( "The line of symmetry is $\"highlight%28x+=+-1%29\"$ and the maximum value is $\"highlight%28-9%29\"$ .
\n" ); document.write( "The graph has a maximum value because a < 0.
\n" ); document.write( "here's the graph:
