Let a, b in R be such that the function ...

Let `a, b in R` be such that the function f given by f(x)= ln `|x|+bx^(2)+ax, x ne0` has extreme values at `x=-1 and x=2`
Statemet-I : f has local maximum at `x=-1 and x=2.`
Statement- II: `a=(1)/(2),b=(-1)/(4)`

A

Statement-I is fasle, Statement-II is true

B

Statement-1 is true, statement-2 is not a correct explanation for Statement-1.

C

Statement-I is true, Statement-II is true, Statement -II is not a correct explanation for Statement-I

D

Statement-I is true, statement-II is false
