Use the properties of limits to help decide whether the limit exists. If the limit exists, find its value.\\
$\lim_{x \to \infty} \frac{6x^3 - 4x - 7}{4x^2 - 9x - 9}$ \\
Select the correct choice below and, if necessary, fill in the answer box within your choice.\\
A. $\lim_{x \to \infty} \frac{6x^3 - 4x - 7}{4x^2 - 9x - 9} = $\\
B. The limit does not exist and is neither $\infty$ nor $-\infty$.
