Look at how the y values change. If each is a constant multiple of the previous, then it is an exponential function.
\n" ); document.write( "4*3=12
\n" ); document.write( "12*3=36
\n" ); document.write( "36*3=108
\n" ); document.write( "Each value is the previous times 3, so it is an exponential function.
\n" ); document.write( "
\n" );
