AP Calculus Review: https://www.youtube.com/c/MrHelpfulNotHurtful/playlists?view=50&sort=dd&shelf_id=1
In this video we explore three situations where a limit does not exist:
1) When the function approaches two different values from the left and right of a given x-value.
2) When the value of a function is unbounded (infinity) near a given x-value.
3) When the value of the function oscillates (switches back and forth) near a given x-value.
