The curve is $\"\"$ .

Graph the curve $\"\"$ .

$\"\"$

Observe the graph, it is clear that the $\"\"$ intecepts are at the points $\"\"$ and $\"\"$ .

Area of the region under these limits lies above $\"\"$ axis only.

Use these $\"\"$ intecepts values as limits of the integration limits to find the area of the region.

Therefore,
