(Review) When we want to express end behavior with words instead of limits
Instead of lim𝑥→−∞𝑓𝑥 , we can say: "As the input values of 𝑓𝑥 decrease without bound…"
Instead of lim𝑥→∞𝑓𝑥, we can say: "As the input values of 𝑓𝑥 increase without bound…"
Instead of =∞, we can say: "…the output values increase without bound."
Instead of =−∞, we can say: "…the output values decrease without bound."
Example: Determine the end behavior of 𝑓𝑥=−4𝑥3+𝑥2−5𝑥−6
