I found:

#### Explanation:

You identify the vertical asymptotes by setting the denominator equal to zero: this allows you to see which

So, set the denominator equal to zero:

So your function cannot accept these values for

The two vertical lines of equations:

will be your "forbidden" lines or vertical asymptotes.

Graphically:
