If $f(x)=\left\{\begin{matrix}x+2&,&x≥2\\3.99999&,&x<2\end{matrix}\right.$ then which option is wrong |
$\underset{x→2}{\lim}f(x)=4$ $\underset{x→2^+}{\lim}f(x)=4$ $\underset{x→2^-}{\lim}f(x)=3.99999$ $\underset{x→2^+}{\lim}f(x)≠\underset{x→2^-}{\lim}f(x)$ |
$\underset{x→2}{\lim}f(x)=4$ |
$\underset{x→2^+}{\lim}f(x)=\underset{x→2^+}{\lim}(x+2)=4$ $\underset{x→2^-}{\lim}f(x)=\underset{x→2^-}{\lim}(3.99999)=3.99999$ |
