![∫f(x)dx=2⇒∫_1 ^3 [2−f(x)]dx=2(3−1)−2=2](https://www.tinkutara.com/question/Q95631.png)
$$\int\mathrm{f}\left(\mathrm{x}\right)\mathrm{dx}=\mathrm{2}\Rightarrow\int_{\mathrm{1}} ^{\mathrm{3}} \left[\mathrm{2}−\mathrm{f}\left(\mathrm{x}\right)\right]\mathrm{dx}=\mathrm{2}\left(\mathrm{3}−\mathrm{1}\right)−\mathrm{2}=\mathrm{2} \\ $$
