9 The curve \(C\) has equation
$$y = \frac { 5 x ^ { 2 } + 5 x + 1 } { x ^ { 2 } + x + 1 } .$$
- Find the equation of the asymptote of \(C\).
- Show that, for all real values of \(x , - \frac { 1 } { 3 } \leqslant y < 5\).
- Find the coordinates of any stationary points of \(C\).
- Sketch \(C\), stating the coordinates of any intersections with the \(y\)-axis.
