The set of points where the function f(x)=|x-1| e^ x is differentiable, is

Options

  1. AR
  2. BR- 1
  3. CR- -1
  4. DR- 0

Correct answer

B. R- 1

Step-by-step solution

Since, |x-1| is not differentiable at x=1 . So, f(x)=|x-1| e^ x is not differentiable at x=1 , Hence, the required set is R- 1 .
