\n" ); document.write( "\"f%28x%29=x%5E2%2B28\"\r
\n" ); document.write( "\n" ); document.write( "\"f%283y%29=2f%28y%29\"\r
\n" ); document.write( "\n" ); document.write( "\"%283y%29%5E2%2B28=2%28y%5E2%2B28%29\"
\n" ); document.write( "\"9y%5E2%2B28=2y%5E2%2B56\"
\n" ); document.write( "\"9y%5E2-2y%5E2=56-28\"
\n" ); document.write( "\"7y%5E2=28\"
\n" ); document.write( "\"y%5E2=4\"
\n" ); document.write( "\"y=2\" or \"y=-2\"\r
\n" ); document.write( "\n" ); document.write( "so, the one possible value of \"y\" is: C)\"2\"
