Question 28
DifferentiationFind the minimum value of y = 3x2 − x − 6.
- A.−6 1/6
- B.−6 1/12
- C.−6
- D.0
Show the answer and explanation
Answer: B (−6 1/12)
Explanation
dy/dx = 6x − 1 = 0 at x = 1/6; y = 3/36 − 1/6 − 6 = −6 1/12.
Find the minimum value of y = 3x2 − x − 6.
Answer: B (−6 1/12)
dy/dx = 6x − 1 = 0 at x = 1/6; y = 3/36 − 1/6 − 6 = −6 1/12.
