7 A curve has equation \(y = \frac { 5 x - 9 } { ( 2 x - 3 ) ( 2 x + 7 ) }\).
- Write down the equations of the two vertical asymptotes and the one horizontal asymptote.
- Describe the behaviour of the curve for large positive and large negative values of \(x\), justifying your answers.
- Sketch the curve.
- Solve the inequality \(\frac { 5 x - 9 } { ( 2 x - 3 ) ( 2 x + 7 ) } \leqslant 0\).
