Is f(x) continuous at x = a, and why?

• No, $\lim_{x\rightarrow a^-}f\left(x\right)\ne\lim_{x\rightarrow a^+}f\left(x\right)$

• No, $\lim_{x\rightarrow a}f\left(x\right)\ne f\left(a\right)$

• Yes, $\lim_{x\rightarrow a^-}f\left(x\right)=\lim_{x\rightarrow a^+}f\left(x\right)$

• Yes, $\lim_{x\rightarrow a}f\left(x\right)=f\left(a\right)$
