Write the number of points where f(x)...

Write the number of points where `f(x)=|x|+|x-1|` is continuous but not differentiable.

Text Solution

Verified by Experts

Consider the given function. `f(x)=∣x∣+|x-1∣`
Since, it is an absolute function. So, it a continuous function.
From the graph of this function, it is clear that
the function f(x) is not differentiable at `x=0` and `x=1`.
Hence, points `0,1` where the function` f(x) `is non-differentiable.
