As we learnt,

 

Condition for definite integration -

f\left ( x \right ) must be continuous between a and b.
 

- wherein

\int_{a}^{b}f\left ( x \right )dx=

\left ( F\left ( b \right )+c \right )-\left ( F\left ( a \right )+c \right )

\Rightarrow F\left ( b \right )+X-F\left ( a \right )-X

\therefore F\left ( b \right )-F\left ( a \right )

 

 Since the function [x] is discontinous ar x = 1,2

 


Option 1)

\int_{0}^{5} x^{2}dx

Option 2)

\int_{0}^{1} \left\{x \right \}dx

Option 3)

\int_{0}^{3} [x]dx

Option 4)

\int_{0}^{2} xdx
