Write an equation that expresses the fact that a function f is continuous at the number 2. \lim _{2\rightarrow x}f(2)=f(x) \lim _{x \rightarrow 2} \bigcirc f(2)=f(x) \lim _{2 \rightarrow x}

\bigcirc f(x)=f(2) \lim _{x \rightarrow 2} \rho f(x)=f(2) \lim _{x \rightarrow 2^{+}} \operatorname{lif}_{x \rightarrow 2^{-}}=f(2)
