`        what is the integrand of [x2-1] upperlimit-2,lower limit-0 where [ ] represents greatest integer function`

```										From the graph , y+1 = x2 , we can say
between x=(0,1)  y takes value of -1
x=(1,1.414)        y takes value of 0
x=(1.414,1.732)  y takes value of 1
x=(1.732,2)        y takes value of 2
integrating in these limits gives
I = int ( -dx) + int ( 0*dx) + int ( dx) + int ( 2*dx) with above limits respecively
I = 1.732 - 1.414 = 0.218

integration is the area under the graph so its basically the area of the rectangle tht is 1*-1=1
