The value of C ( if exists ) in Lagrange...

The value of C ( if exists ) in Lagrange's theorem for the function |x| in the interval [-1,1] is

A

0

B

`1//2`

C

`-1//2`

D

non-existent in the internal

Text Solution

Verified by Experts

The correct Answer is:
D
f(x) is not differentiable at `x=0 in (-1,1)`. So Largrange's theorem is not applicable. Hence, c does not exist.
