Question

The value of $\underset{-2}{\overset{2}{\int }}|x|dx$

• A. $2$
• B. $4$
• C. $8$
• D. none of these

Answer 1

The correct option is B $4$

Now,

$\underset{-2}{\overset{2}{\int }}|x|dx$

$=2\underset{0}{\overset{2}{\int }}xdx$ [ Since $|x|$ is an even function]

$={\left[x^2\right]}_0^2$

$=4$.
