The curve equation is .
Graph :
\Graph the curve .
Observe the graph.
\Locate the points for which the curve touches the axis.
The curve touches the axis at
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 area of the region is
\Power rule of integration: .
Area of the region under these limits lies above axis is
.
Area of the region under these limits lies above axis is
.
