\n" );
document.write( "Hi
\n" );
document.write( " h(t) metres represents the height of a batted baseball as a function of time, t seconds, 
\n" );
document.write( "\"since the ball was hit\"
\n" );
document.write( "h(t) = -2.1(t-2.4)^2 + 13  
\n" );
document.write( "h(0) = -2.1)-2.4)^2 + 13  = 1.1 to nearest tenth of metre
\n" );
document.write( "h(1) = -2.1(-1.4)^2 + 13  = 8.9 nearest tenth of metre
\n" );
document.write( "
\n" );
document.write( " \n" );
