$lim_{r \to - 3} - \frac{3}{r + 3}$

Step 1

Consider the left sided limit.

$lim_{r \to {(- 3)}^{-}} - \frac{3}{r + 3}$

Step 2

As the $r$ values approach $- 3$ from the left, the function values increase without bound.

$\infty$

Step 3

Consider the right sided limit.

$lim_{r \to {(- 3)}^{+}} - \frac{3}{r + 3}$

Step 4

As the $r$ values approach $- 3$ from the right, the function values decrease without bound.

$- \infty$

Step 5

Since the left sided and right sided limits are not equal, the limit does not exist.

$Does not exist$
