Column $I$Column $II$
$A$. $x|x|$$I$. Strictly increasing and continuous in $(-1,1)$
$B$. $\sqrt{|x|}$$II$. Continuous but not differentiable in $(-1,1)$
$C$. $x+[x]$$III$. Differentiable in $(-1,1)$
$D$. $|x-1|+|x+1|+|x|$$IV$. Differentiable in $(-1,0) \cup (0,1)$
$V$. Strictly increasing and not differentiable in $(-1,1)$
