MHT CET2007MathematicsContinuity and Differentiability
The set of points where the function f(x)=|x-1| e^ x is differentiable, is
Options
- AR
- BR- 1
- CR- -1
- 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 .
