The diagram shows the curve with equation \(y = (x - \log_{10} x)^2\), \(x > 0\).
- Copy and complete the table below for points on the curve, giving the \(y\) values to 2 decimal places.
[2]
The shaded region is bounded by the curve, the \(x\)-axis and the lines \(x = 2\) and \(x = 6\).
- Use the trapezium rule with all the values in your table to estimate the area of the shaded region. [3]
- State, with a reason, whether your answer to part (b) is an under-estimate or an over-estimate of the true area. [2]
