### Question 14: State the Domain of the Following Function

**Graph Description:**

The provided graph illustrates a function with significant features to be examined:

- The x-axis ranges from -6 to 6, while the y-axis ranges from -4 to 4.
- There is a vertical asymptote at \(x = -2\), suggesting that the function is undefined there.
- The graph shows that the function approaches \(y = \infty\) as \(x\) approaches -2 from the left, and approaches \(y = -\infty\) as \(x\) approaches -2 from the right.
- The function is continuous from \(x = -6\) to \(x = -2\), excluding \(x = -2\).
- For \(x > -2\), the function resumes and is continuous, with an open circle (indicating discontinuity) at \((0, 0)\).
- The function is defined at \( (1, 3) \), marked by a solid dot at this coordinate.

#### Domain:
The domain of the function includes all real numbers except \(x = -2\) due to the vertical asymptote, and \(x = 0\) because of the open circle (hole in the graph).

**Mathematically, the domain is:**

\[ (-\infty, -2) \cup (-2, 0) \cup (0, \infty) \]

This covers the intervals where the function is defined.
