\n" );
document.write( "Hi
\n" );
document.write( "f(x)=x+4 and g(x)=x^2 -4
\n" );
document.write( " (f+g)(x) = x+4 + x^2 - 4 = x^2 + x
\n" );
document.write( " (f+g)(x) = x^2 + x
\n" );
document.write( " (f+g)(2) = 2^2 + 2 = 6\r
\n" );
document.write( "\n" );
document.write( "f(x)=x^2 -16 and g(x)=4-x
\n" );
document.write( " (f+g)(x) =  x^2 - 16 + 4- x 
\n" );
document.write( "(f+g)(x) = x^2 -x -12
\n" );
document.write( "(f+g)(-3) = (-3)^2 -(-3) -12 = 0 \n" );
document.write( "

\n" );
