**Graphing Rational Functions Using Transformations**

8) **Task:** Graph the rational function \( R(x) = \frac{2}{(x-3)^2} \) using transformations. Determine the domain, range, asymptotes, and intercepts.

**Explanation and Steps:**

1. **Identify the Basic Function:** 
   The function given is derived from the basic rational function \( f(x) = \frac{1}{x^2} \).

2. **Transformations:**
   - **Horizontal Shift:** The function is horizontally shifted 3 units to the right, resulting in the transformation \( \frac{1}{(x-3)^2} \).
   - **Vertical Stretch:** The function is vertically stretched by a factor of 2, giving \( R(x) = \frac{2}{(x-3)^2} \).

3. **Domain:**
   - The function is undefined at \( x = 3 \) due to division by zero in the denominator.
   - **Domain:** \( x \in (-\infty, 3) \cup (3, \infty) \)

4. **Range:**
   - Since \(\frac{2}{(x-3)^2}\) is always positive, the range is all positive values.
   - **Range:** \( y \in (0, \infty) \)

5. **Asymptotes:**
   - **Vertical Asymptote:** At \( x = 3 \), the function is undefined, making it a vertical asymptote.
   - **Horizontal Asymptote:** As \( x \to \pm\infty \), \( R(x) \to 0 \), making \( y = 0 \) a horizontal asymptote.

6. **Intercepts:**
   - **X-Intercept:** No x-intercept, as the function does not cross the x-axis.
   - **Y-Intercept:** Plugging in \( x = 0 \) provides the y-intercept \( R(0) = \frac{2}{(0-3)^2} = \frac{2}{9} \).

7. **Graph Description:**
   - The graph shifts right to \( x = 3 \) and opens upwards.
   - It approaches but never touches the x-axis (horizontal asymptote) and has a vertical asymptote at \(
