Without graphing find the vertex
\n" ); document.write( "
\r\n" );
document.write( "\"%22f%28x%29%22=-%28x%2B5%29%5E2%2B5\"\r\n" );
document.write( "\r\n" );
document.write( "The vertex of \r\n" );
document.write( "\r\n" );
document.write( "\"%22f%28x%29%22=a%28x-h%29%5E2%2Bk\" is the point \"%22%28h%2Ck%29%22\"\r\n" );
document.write( "\r\n" );
document.write( "In your problem\r\n" );
document.write( "\r\n" );
document.write( "\"%22f%28x%29%22=-1%28x%2B5%29%5E2%2B5\"\r\n" );
document.write( "\r\n" );
document.write( "\"a=-1\"\r\n" );
document.write( "\"-h=%22%22%2B5\" so \"h=-5\"\r\n" );
document.write( "\"%22%22%2Bk=%22%22%2B5\" so \"k=5\"\r\n" );
document.write( "\r\n" );
document.write( "So the vertex = \"%22%28h%2Ck%29%22=%22%28-5%2C5%29%22\"\r\n" );
