The graph shows two vertical asymptotes at $x = -2$ and $x = 2$. These are the points where the function approaches infinity, as the curve gets closer to these vertical lines without crossing them.

So, the $x$-values for the vertical asymptotes are: $x = -2, 2$

Here are 5 related questions:

1. What causes vertical asymptotes in a function?
2. How can you determine vertical asymptotes algebraically?
3. What is the difference between vertical and horizontal asymptotes?
4. Can a function have more than two vertical asymptotes?
5. How do vertical asymptotes affect the domain of a function?

Tip: A vertical asymptote occurs when the denominator of a function approaches zero, making the function undefined at that point.
