If this is 4/(x+2) then there is a vertical asymptote at x=-2, because that makes the denominator 0.
\n" ); document.write( "the y-intercept is at (0, 2)
\n" ); document.write( "there is a horizontal asymptote at y=0, approaching from the positive side at positive x and from the negative side with negative x.
\n" ); document.write( "The range is from -oo to +oo, The domain is all x except x= -2\r

\n" ); document.write( "\n" ); document.write( "If it is (4/x)+2, then it has a vertical asymptote at x=0, it is displaced upwards 2 units, making the horizontal asymptote +2 and the same general shape, shifted upward 2 and to the right 2.
