The diagram shows part of the curve \(y = x \mathrm { e } ^ { - x }\). The shaded region \(R\) is bounded by the curve and by the lines \(x = 2 , x = 3\) and \(y = 0\).
- Use the trapezium rule with two intervals to estimate the area of \(R\), giving your answer correct to 2 decimal places.
- State, with a reason, whether the trapezium rule gives an under-estimate or an over-estimate of the true value of the area of \(R\).
