$\"\"$

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

Graph the function : $\"\"$

$\"\"$

Rolle $\"\"$ s theorem :

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

$\"\"$ on interval $\"\"$ .

Find the value of the function at the endpoints of the interval.

$\"\"$

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