document.write( "Hi
\n" );
document.write( "Finding f(2) is the result of simply substituting the value of 2 for x
\n" );
document.write( "a) f(2) = - x + 3 = 1
\n" );
document.write( "b) f(2) = 2x^3 - 7x^2 + 8 = 16 -28 +8 = -4
\n" );
document.write( "c) f(x) = |x + 3| - 9 = 5 - 9 = -4\r
\n" );
document.write( "\n" );
document.write( "(note: absolute value sign is 'uppercase' \ on the key board) \n" );
document.write( "

\n" );
