Calculate $\underset{x-}{lim}(-3z^5).$ If the limit does not exist because the function has infinite behavior, use limit notation to describe the infinite behavior.

$\underset{a-}{lim}(-3z^8)$ does not exist, bail the infrite behavior can best be described as $\underset{x-}{lim}(-3x^5).$

$\underset{x-}{lim}(-3x^5)$ does not exist, bact the infinite betwerior can best be described as $\underset{x-}{lim}(-3x^2)-.$

$\underset{x-}{lim}(-3x^3)=0$

$\underset{x-}{lim}(-3x^5)=$
