#### Answer

This means that
$$\lim_{x\to \infty}\frac{f(x)}{g(x)}=\infty.$$

#### Work Step by Step

This means that if we take the limit of the ratio of $f$ and $g$ as $x\to \infty$ goes to infinity by definition of the term of growing faster or, in other words,
$$\lim_{x\to \infty}\frac{f(x)}{g(x)}=\infty.$$
