$\underset{x\to 4+}{\mathrm{l}\mathrm{i}\mathrm{m}}f\left(x\right)$exists but$\underset{x\to 4-}{\mathrm{l}\mathrm{i}\mathrm{m}}f\left(x\right)$does not exist

$f$is continuous at$x=4$

$\underset{x\to 4-}{\mathrm{l}\mathrm{i}\mathrm{m}}f\left(x\right)$exists but$\underset{x\to 4+}{\mathrm{l}\mathrm{i}\mathrm{m}}f\left(x\right)$does not exist

Both$\underset{x\to 4-}{\mathrm{l}\mathrm{i}\mathrm{m}}f\left(x\right)$and$\underset{x\to 4+}{\mathrm{l}\mathrm{i}\mathrm{m}}f\left(x\right)$exist but are not equal
