$\int\limits_0^2(|x|+|x-2|)dx =$
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 4
Integral:
$\displaystyle \int_{0}^{2} \left(|x| + |x-2|\right)\,dx$
On $[0,2]$:
$|x| = x$ (since $x\ge 0$)
$|x-2| = 2 - x$ (since $x-2\le 0$)
So the integrand becomes:
$x + (2 - x) = 2$
Integral:
$\displaystyle \int_{0}^{2} 2\,dx = 2[x]_{0}^{2} = 2(2 - 0) = 4$
Answer = 4
