Write the points where `f\ (x)=|(log)_e x|` is not differentiable.

Text Solution

Verified by Experts

Consider the given function. `f(x)=∣logx∣`
Since, it is an absolute function.
So, it a continuous function.
From Its graph, it is clear that the function `f(x)` is not differentiable at `x=1`.
Hence, points `1` where the function `f(x)` is non-differentiable.
