Explain why Lagrange’s mean value theorem is not applicable to the following functions in the respective intervals:
`f(x) = |3x + 1|, x ∈ [-1, 3]`
उत्तर
f(x) = |3x + 1|, x ∈ [-1, 3]
The function is not differentiable at x = `(-1)/3`
So Lagrange’s mean value theorem is not applicable in the given interval.
