6: Conditions
    • x − 6 ≠ 0,
    • x − 2 ≥ 0
give the domain

D( f ) = [2,6) ∪ (6,∞).

Now it is time to find limits at 2 from the right, at 6 from the left and from the right, and at ∞.

Hint on limit at 2 from the right
Hint on limit at 6 from the left
Hint on limit at 6 from the right
Hint on limit at ∞
