\n" ); document.write( "\n" ); document.write( "\"x\"|\"y\"\r
\n" ); document.write( "\n" ); document.write( "\"1\"|\"3.2\"=>\"3.2=3.2%2A1\"=>\"3.2=3.2%2A1%5E2\"
\n" ); document.write( "\"2\"|\"12.8\"=>\"12.8=3.2%2A4\"=>\"12.8=3.2%2A2%5E2\"
\n" ); document.write( "\"3\"|\"28.8\"=>\"28.8=3.2%2A9\"=>\"28.8=3.2%2A3%5E2\"
\n" ); document.write( "\"4\"|\"51.2\"=>\"51.2=3.2%2A16\"=>\"51.2=3.2%2A4%5E2\"
\n" ); document.write( "\"5\"|\"80\"=>\"80=3.2%2A25\"=>\"80=3.2%2A5%5E2\"\r
\n" ); document.write( "\n" ); document.write( "so, we have \"y=3.2x%5E2\"\r
\n" ); document.write( "\n" ); document.write( "your answer is:
\n" ); document.write( "c. \"y\" is proportional to \"x%5E2\"
\n" ); document.write( "
