Answer:
Answer to all three points is NO.
Step-by-step explanation:
Case 1:
[tex]\lim_{x \to \>>1} f(x)= 1[/tex]
Answer : NO, It is important to note that the even if function is not defined, the limit of function can exist and it doesn't mean that f(x) must necessarily be defined at x = 1
Case 2:
Answer : No, because it could be a piece wise function even if f is defined, where f(1) might have different values while approaching from right and left side of limits.
Case 3:
Answer: No, value of f(1) can not be concluded
