Hi, I need help on this one problem: ( I can't type in the format the problem is given, so hopefully it'll be understandable.)
The question states:
Evaluate or determine that the limit does not exist for each of the limits (a) lim x--> d- f(x), (b) lim x-->d+ f(x)
f(x)={ 1/(x+1), for x>-1
x^2-3x, for x<=(less than and equal) -1
d=-1
I think the answer for (a) is 4, and (b) is 4 also, but there are no answer choices (this is multiple choice) for that. The closest is (a) 4, (b) does not exist. I don't understand why (b) is does not exist.
The answer choices are:
1) (a) does not exist
(b) 4
and
2) (a) 4
(b)Does not exist.
Any help would be appreciated, thanks!
oh right, I forgot about that, yes, d=-1.

The answer choices are (should have put them up in the first post) are:
1) (a) does not exist
(b) 4
and
2) (a) 4
(b)Does not exist.
