Step-by-step explanation
Dividing the numerator and denominator by the highest denominator power (x^2):

Applying the following property:
![\lim _(x\to a)\mleft[(f\left(x\right))/(g\left(x\right))\mright]=(\lim_(x\to a)f\left(x\right))/(\lim_(x\to a)g\left(x\right)),\: \quad \lim _(x\to a)g\mleft(x\mright)\\e0](https://img.qammunity.org/2023/formulas/mathematics/high-school/234pzb84wysnng8wqafalkqa9iusyfn4w5.png)



Now, we need to apply the same steps to x-> ∞



Simplifying:

![\lim _(x\to a)\mleft[(f\left(x\right))/(g\left(x\right))\mright]=(\lim_(x\to a)f\left(x\right))/(\lim_(x\to a)g\left(x\right)),\: \quad \lim _(x\to a)g\mleft(x\mright)\\e0](https://img.qammunity.org/2023/formulas/mathematics/high-school/234pzb84wysnng8wqafalkqa9iusyfn4w5.png)





In conclusion, the appropiate end behavior is as follows:
