The function given is $y = \frac{1}{3} f(x - 3) - 5$, which represents a transformed version of a function $f(x)$. The transformation consists of:

1. Horizontal Shift: $x - 3$ shifts the graph 3 units to the right.
2. Vertical Scaling: The factor $\frac{1}{3}$ compresses the graph vertically by a factor of 3.
3. Vertical Shift: The $-5$ moves the entire graph down by 5 units.

To draw the graph, I would need more details about the specific function $f(x)$. If $f(x)$ is not defined, I can draw a general sketch based on the transformations of any standard function. Should I proceed with a specific type of function, like $f(x) = x^2$ (parabola), or do you have another function in mind?
