$\int_0^2|2 x-3| d x=$

$\int_0^2|2 x-3| d x=$
  1. $\frac{3}{10}$
  2. $\frac{5}{2}$
  3. $\frac{10}{3}$
  4. $\frac{2}{5}$

Solution

Let When $x=\frac{3}{2}, 2 x-3=0$ $\begin{aligned} & \therefore \mathrm{I}=\int_0^{3 / 2}(3-2 \mathrm{x}) \mathrm{dx}+\int_{\frac{3}{2}}^2(2 \mathrm{x}-3) \mathrm{dx}=[3 \mathrm{x}]_0^{3 / 2}-\frac{2}{2}\left[\mathrm{x}^2\right]_{3 / 2}^2-[3 \mathrm{x}]_{3 / 2}^2 \\ & =\left(\frac{9}{2}\right)-\left(\frac{9}{4}\right)+\left(4-\frac{9}{4}\right)-3\left(2-\frac{3}{2}\right)=\frac{5}{2} \end{aligned}$
