A) \[a=2,\ b=0\]
B) \[a=1,\ b=-1\]
C) \[a=4,\ b=2\]
D) All the above
Correct Answer: D
Solution :
\[\underset{x\to 1-}{\mathop{\lim }}\,f(x)=a-b,\,\,\underset{x\to 1+}{\mathop{\lim }}\,f(x)=2\,\,\Rightarrow a-b=2\] All the given sets of a, b make \[f(x)\] continuous at x=1.You need to login to perform this action.
