Question

left hand limit defination​

Answer 1

Answer:

A left-hand limit means the limit of a function as it approaches from the left-hand side.

On the other hand, A right-hand limit means the limit of a function as it approaches from the right-hand side.

When getting the limit of a function as it approaches a number, the idea is to check the behavior of the function as it approaches the number. We substitute values as close as possible to the number being approached.

The closest number is the number being approached itself. Hence, one usually just substitutes the number being approached to get the limit.

However, we cannot do this if the resulting value is undefined.

But we can still check its behavior as it approaches from one side.
