The curve C has equation \(y = \frac{x^2 + 2x - 15}{x - 2}\).

1. Find the equations of the asymptotes of C.
2. Show that C has no stationary points.
3. Sketch C, stating the coordinates of the intersections with the axes.
4. Sketch the curve with equation \(y = \left| \frac{x^2 - 2x - 15}{x - 2} \right|\).
5. Find the set of values of \(x\) for which \(\left| \frac{2x^2 + 4x - 30}{x - 2} \right| < 15\).
