Let

$f(x)=\frac{1}{x+3}$

Find each point of discontinuity of $f,$ and for each give the value of the point of discontinuity and evaluate the indicated one$-$sided limits$.$ NOTE: Use 'INF' for $$ and $\text{'}-$INF' for $-.$

If you have more than one point, give them in numerical order, from smallest to largest.

If you have extra boxes, fill each in with an $\text{'}x\text{'}.$

Point $1$: $C=$

$\underset{x{C}^{-}}{lim}f(x)=$

$\underset{x{C}^{+}}{lim}f(x)=$

$$

Point $2$: $C=$

$\underset{x{C}^{-}}{lim}f(x)=$

$\underset{x{C}^{+}}{lim}f(x)=$

$$

Point $3$: $C=$
