how to know when to apply left hand limit and right hand limit in limits?
Dear Student,
When we have to find left hand limit we have to check at the values of say x = 2 , then for left hand limit we have to check at x= 2- and for right hand limit we have to check at x= 2+.
So it depends upon the type of question . If we have to check the continuity we have to check both limits.
For example:
So here since both limits are unequal it is not continuous.
