If `f :[ - 2a, 2a] to R` is an odd function such that `f (x) = f (2a -x) ` for ` x in [a, 2a].` If the left hand derivative of f (x) at x =a is zero, then show that the left hand derivative of `f (x) at x =-a` is also zero

Text Solution

Verified by Experts

The correct Answer is:
`therefore f'(-a^(0)) =0`
