- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given, y=ax-bx-1x-4 …i has turning point P2,-1 ∴ Point P satisfy the equation i ⇒-1=2a-b2-12-4=2a-b-2 ⇒2a-b=2 …ii As we know turning point of function is a point where f'x=0. So, let's find dydx From equation i, yx-1x-4=ax-b…
