**Graph the Function**

### Function
\[ y = 5 \left(\frac{1}{3}\right)^x \]

### Domain and Range
- **Domain**: All real numbers
- **Range**: y > 0 (the graph never touches the x-axis but comes infinitely close, indicating that the value of \( y \) is always positive)

### Asymptote
- **Horizontal Asymptote**: y = 0

### Labeled Points
The graph includes the following points:
- \( (0, 5) \)
- \( (1, \frac{5}{3}) \)

These points are plotted on a Cartesian plane.

### Graph Explanation
The given image displays a Cartesian grid with the function \( y = 5 \left(\frac{1}{3}\right)^x \) plotted. This function represents an exponential decay curve. Below are key points of the graph:

1. **Intercepts**: 
   - The graph crosses the y-axis at point \( (0, 5) \), which is the y-intercept.

2. **Behavior**:
   - As \( x \) increases, \( y \) decreases rapidly towards 0 but never reaches it, showcasing the horizontal asymptote at y = 0.
   - As \( x \) decreases, \( y \) increases without bound.

3. **Appearance**:
   - The curve starts from the y-intercept at \( (0, 5) \) and moves downward as it extends to the right along the x-axis.   
   - There are marked points at \( (0, 5) \) and \( (1, \frac{5}{3}) \) for clarification and reference.

This exercise is an example of graphing exponential functions and understanding their properties, such as domain, range, and asymptotes.
