The problem asks to graph the linear function and determine its domain and range. The function provided is:

\[
f(x) = -5x + 3
\]

### Step 1: Graphing the Function
This is a linear function in the slope-intercept form \(f(x) = mx + b\), where:
- \(m = -5\) is the slope, indicating the steepness and direction of the line.
- \(b = 3\) is the y-intercept, where the line crosses the y-axis.

1. **Plot the y-intercept**: The point \((0, 3)\) is on the graph.
2. **Use the slope**: Since the slope is \(-5\), for every 1 unit increase in \(x\), \(f(x)\) decreases by 5 units. So from \((0, 3)\), move 1 unit to the right and 5 units down to plot another point \((1, -2)\).
3. **Draw the line**: Connect the points to extend the line.

### Step 2: Domain and Range
- **Domain**: The domain of a linear function is all real numbers because the function is defined for any value of \(x\).
  \[
  \text{Domain} = (-\infty, \infty)
  \]
- **Range**: Similarly, the range of a linear function is all real numbers because as \(x\) approaches infinity or negative infinity, \(f(x)\) can take any value.
  \[
  \text{Range} = (-\infty, \infty)
  \]
