The function $\"\"$ over the interval $\"\"$ .

Graph the function : $\"\"$ .

$\"\"$

Rolle $\"\"$ s theorem :

The function is continuous on $\"\"$ , differentiable on $\"\"$ and $\"\"$ .

$\"\"$ is continuous on $\"\"$ .

But the function $\"\"$ is not differentiable at $\"\"$ .

$\"\"$ is not differentiable on $\"\"$ .

Hence, Rolle $\"\"$ s theorem is not satisfied.
