Explanations :

Remember: A function can have limits even if a point on the function is not defined ( open circle).

Remember: When you see a discontinuity in a function, check for both left and right-hand limits.

Remember: When you see a discontinuity in a function, check for both left and right-hand limits.

Point: This is an example when a function has a limit that is different from the value of the function at that point.
