8-10.

Explain in one or two sentences how examining the dominant term of a function can help find the limit of the function as $x → ∞$ or as $x → −∞$. Enter this idea into your Tool Kit with an example.

You only need to consider the dominant term for the limit since all other terms would be insignificant when $x→∞$ or when $x→−∞$.
