when impulse is asked when should we use (mv-mu)and when should we use (mu-mv)please give me the answer

This answer depends on the frame of reference in consideration.
Eg. suppose we are required to find the impulse tranferred on a bat by a ball, so there we will use:
where as the impuse on the ball by bat wil be mu-mv
as in this case the force is transmitted to the bat by ball in the direction of initial velocity of ball.
