document.write( "(a)  Evaluate each function f(x) and g(x) separately at x= -2; then  take the difference f(-2) - g(-2).\r\n" );

document.write( "(b)  Evaluate each function f(x) and g(x) separately at x= -2; then  take the product  f(-2)*g(-2).\r\n" );

document.write( "\r\n" );
document.write( "(c)  (f-g)(x) = by the definition = f(x) - g(x) = (4x^2 + 2x -8) - (1 - x) = 4x^2 + 3x -9.\r\n" );
