Text Solution

Verified by Experts

The correct Answer is:
6
Draw the given region point of intersection of `y=x^(2)+1`
`y=x+1`
`x+1=x^(2)+1`
`x=0,1`

`"Required area "OABCDE=overset(1)underset(0)int(x^(2)+1)dx+overset(2)underset(1)int(x+1)dx`
`=((x^(3))/(3)+x)_(0)^(1)+((x^(2))/(2)+x)_(1)^(2)=(23)/(6)` sq. units
