Question 38
DifferentiationEvaluate: limx→−2 (x3 + 8)/(x + 2)
- A.8
- B.2
- C.4
- D.12
Show the answer and explanation
Answer: D (12)
Explanation
x³ + 8 = (x + 2)(x² − 2x + 4), so the limit is (−2)² − 2(−2) + 4 = 12.
Evaluate: limx→−2 (x3 + 8)/(x + 2)
Answer: D (12)
x³ + 8 = (x + 2)(x² − 2x + 4), so the limit is (−2)² − 2(−2) + 4 = 12.
