10: Conditions
    • x² + 1 > 0,
    • x − 1 > 0,
    • ln(x) + 1 ≠ 0
give the domain

D( f ) = (0,1/e) ∪ (1/e,∞).

Now it is time to find limits at 0 from the right, at 1/e from the left and from the right, and at ∞.

Hint on limit at 0 from the right
Hint on limit at 1/e from the left
Hint on limit at 1/e from the right
Hint on limit at ∞
