Is f continuous at -4? Recall that: lim_{x\rightarrow\left(-4^{-}\right)}f\left(x\right)=2 lim_{x\rightarrow\left(-4^{+}\right)}f\left(x\right)=-2

• Yes the function is continuous at -4.

• No the function is not continuous at -4.

Is $f$ continuous at -6?

Recall that:
$\lim_{x\rightarrow\left(-6^-\right)}f\left(x\right)=\infty$
$\lim_{x\rightarrow\left(-6^+\right)}f\left(x\right)=-\infty$

• Yes the function is continuous at -6.

• No the function is not continuous at -6.
