Use the graph below to decide whether the limit statements are true or false

$\underset{x\to -2}{lim}f\left(x\right)=DNE$
$\underset{x\to -{2}^{+}}{lim}f\left(x\right)=3$
$\underset{x\to -7}{lim}f\left(x\right)=3$
$\underset{x\to \mathrm{\infty }}{lim}f\left(x\right)=-\mathrm{\infty }$
$\underset{x\to 3}{lim}f\left(x\right)=7$
$\underset{x\to -\mathrm{\infty }}{lim}f\left(x\right)=\mathrm{\infty }$

$\underset{x\to -2}{lim}f\left(x\right)=DNE=true$
$\underset{x\to -\mathrm{\infty }}{lim}f\left(x\right)=-\mathrm{\infty }=true$
$\underset{x\to -{2}^{+}}{lim}f\left(x\right)=-\mathrm{\infty }=false$
$\underset{x\to 3}{lim}f\left(x\right)=7=true$
$\underset{x\to -7}{lim}f\left(x\right)=3=true$
$\underset{x\to -\mathrm{\infty }}{lim}f\left(x\right)=\mathrm{\infty }=false$
