The TOTAL shaded area in the diagram below is given by

1. (A)\int_0^3 f(x)\,\mathrm{d}x
2. (B)\left|\int_0^3 f(x)\,\mathrm{d}x\right|
3. (C)\int_0^1 f(x)\,\mathrm{d}x + \int_{-1}^3 f(x)\,\mathrm{d}x
4. (D)\int_0^1 f(x)\,\mathrm{d}x + \left|\int_1^3 f(x)\,\mathrm{d}x\right|

This question uses a figure or table from the paper — you'll see it when you practise.
