Question

use the graph of the rational function to complete the following statement.

as \\(x \
ightarrow -\infty\\), \\(f(x) \
ightarrow \underline{\quad\quad}\\)

as \\(x \
ightarrow -\infty\\), \\(f(x) \
ightarrow \square\\)

<reasoning>

Identify the target behavior

Using the Rational Function End Behavior knowledge point
\[
\text{Find } \lim_{x \to -\infty} f(x)
\]

Analyze the graph's left end

Using the Horizontal Asymptotes knowledge point
\[

$$\begin{aligned} &\text{As } x \to -\infty, \text{ the curve approaches the horizontal line } y = 1.\\ &\text{Thus, } f(x) \to 1. \end{aligned}$$

\]
