22: Conditions
    • x + 1 ≥ 0,
    • the denominator is not zero
give the domain

D( f ) = [−1,0) ∪ (0,∞).

Now it is time to find limits at −1 from the right, at 1 from the left and from the right, and at ∞.

Hint on limit at −1 from the right
Hint on limit at 0 from the left
Hint on limit at 0 from the right
Hint on limit at ∞
