$\"\"$

The function is $\"\"$ and the interval is $\"\"$ .

To find the absolute extreme of function in given region $\"\"$ , sketch the function.

$\"\"$

Observe the graph :

$\"\"$ is absolute minimum point over the interval $\"\"$ .

Right end point $\"\"$ is maximum point over the interval $\"\"$ .

Absolute extrema at end point is not considered.

Hence $\"\"$ is not considered.

$\"\"$

Minimum point is $\"\"$ .
