Please help to answer the following limit to evaluate:

Question

Answer:

A) ____

B) ____

C) ____

Answer 1

(a) Lim f(x) [x -> -1(-)]

Since x is approaching -1 from below, then f(x) = 1/x^2 and the limit is 1/(-1)^2 = 1

(b) Lim f(x) [x -> 1(+)]

Since x is approaching 1 from above, then f(x) = x + 1 and the limit is 1 + 1 = 2

(c) Lim f(x) [x -> 2(-)]

Since x is approaching 2 from below, then f(x) = x + 1 and the limit is 2 + 1 = 3
