$lim_{x \to - 1} \frac{x + 3}{x + 1} \cdot \arctan (x)$

Step 1

Combine $\frac{x + 3}{x + 1}$ and $\arctan (x)$ .

$lim_{x \to - 1} \frac{(x + 3) \arctan (x)}{x + 1}$

Step 2

Since the function approaches $\infty$ from the left and $- \infty$ from the right, the limit does not exist.

$Does not exist$
