A) \[f(x)\]is continuous at \[x=a\]
B) \[f(x)\]is discontinuous at \[x=a\]
C) \[\underset{x\to a}{\mathop{\lim }}\,f(x)=1\]
D) None of these
Correct Answer: B
Solution :
\[\underset{x\to a-}{\mathop{\lim }}\,f(x)=-1,\,\underset{x\to a+}{\mathop{\lim }}\,f(x)=1,\,\,f(a)=1.\]You need to login to perform this action.
