If the extreme value of is then the set of all real values of for which is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Let fx=3x-2x2+1 Differentiating both sides w.r.t. x, we get f'x=3-4x For extreme value, f'x=0 ⇒ 3-4x=0 ⇒ x=34 So, f34=k ⇒ 3×34-2×916+1=k ⇒ 36-18+16=k ⇒ k=34 So,…
