Curve SS has equation y=252x+1y = 2 - \frac{5}{2x+1} where x12x \neq -\frac{1}{2}
(a) Write down an equation of the asymptote to SS that is parallel to
(i) the yy-axis
(ii) the xx-axis
(3)
(b) Find the coordinates of the point where SS crosses
(i) the yy-axis
(ii) the xx-axis
(2)
(c) Using the axes on the page opposite, sketch SS, showing clearly the asymptotes and the coordinates of the points where SS crosses the coordinate axes.
