The places where the function does crazy things like not having a value (indicated by an empty circle), or suddenly jumps from one yvalue to another are called discontinuities (because of them you can't draw the function in a nice line without pen leaving paper). Because they are slightly awry, these places don't have limits, as when x approaches them the function doe *not* settle down to a nice value (which is what the limit is, it asks: 'as x gets close to a, does y get closer to ONE value in particular?' the limit's value is actually this settling down value, call it b).

(1) is incorrect, as the function is nice at x=2 (3) is correct, same reason 4 and 5 are obviously incorrect

Although I say that, I'm not sure about 3 as it may not have a limit approaching it from both sides, so 3 is probably incorrect

it means when x goes to 2 , y =s 2?

Yes. I'm not sure whether it matters that there is no line right of that.

okay, just for clarification. f(x) means y right?
