$$ lim(x\rightarrow \infty)=\infty $$ $$ lim(x\rightarrow -\infty)=\infty$$

Work Step by Step

We look at the term of the highest degree for the polynomial. Doing this, we see that this is a quartic function with a positive coefficient. Thus: $$ lim(x\rightarrow \infty)=\infty $$ $$ lim(x\rightarrow -\infty)=\infty$$
