You can put this solution on YOUR website!
When you found f(2) you got it right, but it's not equal to 2. Look!
\n" ); document.write( " $\"f%28x%29+=+3x%5E2\"$ Subsitute x = 2.
\n" ); document.write( " $\"f%282%29+=+3%282%29%5E2\"$
\n" ); document.write( " $\"f%282%29+=+3%2A4\"$
\n" ); document.write( " $\"highlight%28f%282%29+=+12%29\"$
\n" ); document.write( "Notice that it's f(2) = 12 and not 2 = 12! \n" ); document.write( "

\n" );
