\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(-3) = 8(-3)^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(-3) = 8(9)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(-3) = 72\r
\n" ); document.write( "
\n" ); document.write( "
