How do you know when the limit of a function is undefined?

How do I know that the limit of a function does not exist when I am given a graph or a table?


PLZ HELP!!!|||You know it exists when the graph flows neatly to a particular point -- the limit. If the graph goes to infinity, or if it heads to different values from different sides, or something even messier happens, the limit doesn't exist.





Same idea with a table.





Basically, having a limit is being "well-behaved". Not having a limit is being a teenager ... I mean, being the opposite of "well-behaved". :D :D :D
