If lim x->2^- f(x) = lim x->2^+ = -1, but f(2) = 1, then lim x->2 f(x).
What is the best answer for this limit?
a. is -1.
b. does not exist.
c. is infinite.
d. is 1.
Lets say that .
If , it doesn't have an affect on the value of the limit. Thus
Does this make sense?
With this, determine the correct answer.
