You can put this solution on YOUR website!
$\"f%28x%29=2%28x-2%29%5E2\"$ is in the form $\"f%28x%29=a%28x-h%29%5E2%2Bk\"$ where (h,k) is the vertex and x=h is the line of symmetry. \r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So because h=2 and k=0, the vertex is (2,0) and the line of symmetry is x=2.\r
