Right Hand and Left Hand Limit

The statement x→aˉ means that x is tending to a from the left hand side.

The statement x→a+ means that x is tending to a from the right hand side.

Steps to find left hand limit

Put x = a - h and replace x→aˉ by h→0. Find limit of f(a-h) as h→0

Steps to find right hand limit

Put x = a + h and replace x→a+ by h→0. Find limit of f(a+h) as h→0
