### Task 13: Finding x- and y-intercepts of a Rational Function

**Objective:**
Determine the x- and y-intercepts of the given rational function. If an answer does not exist, enter DNE (Does Not Exist).

**Given Function:**
\[ t(x) = \frac{x^2 - 2x - 24}{x - 9} \]

**Instructions:**

1. **x-intercepts:**
   - Find the points where the function intersects the x-axis.
   - These occur where \( t(x) = 0 \).
   - Thus, solve the equation \( x^2 - 2x - 24 = 0 \).

2. **y-intercept:**
   - Find the point where the function intersects the y-axis.
   - This occurs where \( x = 0 \).
   - Evaluate the function at \( x = 0 \) to find \( t(0) \).

**Input Fields:**

- **x-intercept (x, y) with smaller x-value:** \[ \boxed{\phantom{0}} \]
- **x-intercept (x, y) with larger x-value:** \[ \boxed{\phantom{0}} \]
- **y-intercept (x, y):** \[ \boxed{\phantom{0}} \]

**Options:**
- Optional submission of detailed work to support your answers. Use the "Show My Work (Optional)" section if necessary.

After completing your calculations, submit your answers through the "Submit Answer" button.

> Note: For this function, consider any possible factors or solutions that may not exist by entering DNE.

**Example Explanation:**

1. **Finding x-intercepts:**
   - Factorize the numerator \( x^2 - 2x - 24 \).
   - Solve for \( x \).

2. **Finding y-intercept:**
   - Substitute \( x = 0 \) into the function.
   - Simplify to find \[ t(0) \].

**Submit Answer:**

\[ \boxed{ \text{Submit Answer} } \]
