IntegrationEvaluate ∫12 (x2 − 4x) dx
- A.11/3
- B.3/11
- C.−3/11
- D.−11/3
Show the answer and explanation
Answer: D (−11/3)
Explanation
[x3/3 − 2x2] from 1 to 2 = (8/3 − 8) − (1/3 − 2) = 7/3 − 6 = −11/3.
Evaluate ∫12 (x2 − 4x) dx
Answer: D (−11/3)
[x3/3 − 2x2] from 1 to 2 = (8/3 − 8) − (1/3 − 2) = 7/3 − 6 = −11/3.
