A) \[a=0,b\]and c are any real numbers
B) \[c=0,a=0,b\] is any real number
C) \[b=0,c=0,a\] is any real number
D) \[a=0,b=0,c\] is any real number
Correct Answer: D
Solution :
\[|\sin x|\]and \[{{e}^{|x|}}\] are not differentiable at x = 0 and |x|3 is differentiable at x = 0. \[\therefore \]for f(x) to be differentiable at x = 0, we must have a = 0, b = 0 and c is any real number.
