Identify the target behavior
\[
\text{Right end behavior means analyzing } f(x) \text{ as } x \to \infty.
\]
Analyze the graph's right side
\[
\text{As } x \text{ increases to the right } (x \to \infty)\text{, the curve points downwards indefinitely, meaning } f(x) \to -\infty.
\]
Match with the options
\[
x \to \infty, f(x) \to -\infty
\]
