14: This general power needs to be transformed into its canonical form first:

Conditions
    • ln(2x + 7) > 0,
    • 2x + 7 > 0,
    • x ≠ 0
give the domain

Df ) = (−3,0) ∪ (0,∞).

Now it is time to find limits at −3 from the right, at 0 from the left and from the right, and at ∞.

Hint on limit at −3 from the right
Hint on limit at 0 from the left
Hint on limit at 0 from the right
Hint on limit at ∞
