If _ x 0 ( p 2x + 1 - 2x x + x ) = 1 then the value of ' p ' is
Options
- A2
- B-1
- C1 2
- D1
Correct answer
D. 1
Step-by-step solution
The given limit is _ x 0 ( p 2x + 1 - 2x x + x ) = 1 . Substituting x = 0 , we get the form 0 0 . Applying L'Hospital's rule by differentiating the numerator and the denominator with respect to x : _ x 0 ( 2p 2x + 2 2x 1 + ^2 x ) = 1 Substituting x = 0 into the expression: 2p (0) + 2 (0) 1 + ^2(0) = 1 2p(1) + 0 1 + 1 = 1 2p 2 = 1 p = 1 Answer: 1
