Let’s check out your problem:

Let $f(x)=\frac{3}{x}$.$\newline$Select the correct description of the one-sided limits of $f$ at $x=0$.$\newline$Choose $1$ answer:$\newline$(A) $\lim _{x \rightarrow 0^{+}} f(x)=+\infty$ and $\lim _{x \rightarrow 0^{-}} f(x)=+\infty$$\newline$(B) $\lim _{x \rightarrow 0^{+}} f(x)=+\infty$ and $\lim _{x \rightarrow 0^{-}} f(x)=-\infty$$\newline$(C) $\lim _{x \rightarrow 0^{+}} f(x)=-\infty$ and $\lim _{x \rightarrow 0^{-}} f(x)=+\infty$$\newline$(D) $\lim _{x \rightarrow 0^{+}} f(x)=-\infty$ and $\lim _{x \rightarrow 0^{-}} f(x)=-\infty$
