You can put this solution on YOUR website!
For a(x) = 680*4.3^x you can see that when x = 0, a(0) = 680.
\n" ); document.write( "Thus 680 is the initial amount.
\n" ); document.write( "The 4.3 is the growth factor...when x = 1, a(1) is 680*4.3.
\n" ); document.write( "When x = 2, a(2) = 680*4.3^2 and so on... \n" ); document.write( "

\n" );
