The given function is:

\[
f(x) = -\frac{1}{4} |x - 3|
\]

### 1. Graphing the Function:
This is a transformation of the absolute value function, \( f(x) = |x| \), with the following modifications:
- The \( (x - 3) \) term translates the graph horizontally to the right by 3 units.
- The \( -\frac{1}{4} \) term reflects the graph across the x-axis and compresses it vertically by a factor of 4.

#### Steps to Graph:
- The vertex of the function is at \( (3, 0) \).
- The slope to the left of \( x = 3 \) is \( -\frac{1}{4} \), and to the right of \( x = 3 \), the graph also has a slope of \( -\frac{1}{4} \).

### 2. Domain and Range:
#### **Domain**:
Since the function involves an absolute value and linear operations, the domain is all real numbers:
\[
\text{Domain} = (-\infty, \infty)
\]

#### **Range**:
The graph opens downward due to the negative coefficient \( -\frac{1}{4} \), and the highest point is at the vertex \( (3, 0) \). The range extends from negative infinity up to 0:
\[
\text{Range} = (-\infty, 0]
\]

Would you like me to graph this function, or is there anything you would like to clarify?

### Tip:
When graphing piecewise or absolute value functions, start by identifying the transformations (translations, reflections, stretches/compressions) to easily predict the shape.

Use a graphing utility to graph the function and estimate its domain and range. Then find the domain and range algebraically: f(x) = -1/4 |x - 3|.
