6 The curve \(C\) has equation \(\mathrm { y } = \frac { \mathrm { x } ^ { 2 } + \mathrm { x } - 1 } { \mathrm { x } - 1 }\).
- Find the equations of the asymptotes of \(C\).
- Show that there is no point on \(C\) for which \(1 < y < 5\).
- Find the coordinates of the intersections of \(C\) with the axes, and sketch \(C\).
- Sketch the curve with equation \(\mathrm { y } = \left| \frac { \mathrm { x } ^ { 2 } + \mathrm { x } - 1 } { \mathrm { x } - 1 } \right|\).
