\n" );
document.write( "Re:  Annual Income = I(t) = -0.1t^2+2t where t is time in years
\n" );
document.write( "I(t) = -.1t(t - 20)
\n" );
document.write( "I(0) = 0 & I(20) = O\r
\n" );
document.write( "\n" );
document.write( "I(t) = -0.1t^2+2t  (note: negative coefficient of the squared term)
\n" );
document.write( "graph of this parabola opens downward, with a maximum at 10years (0+20)/2 
\n" );
document.write( "After 10 years, the income begins to decline.
