1. **Problem Statement:** Find the range, amplitude, and period of the function $$y = \cos x - 5$$ and understand its graph.
2. **Recall the cosine function properties:**
- The standard cosine function $$y = \cos x$$ has a range of $$[-1, 1]$$.
- The amplitude is the distance from the midline to a peak, which is $$1$$ for $$\cos x$$.
- The period is the length of one full cycle, which is $$360^\circ$$ or $$2\pi$$ radians.
3. **Effect of vertical shift:**
- The function $$y = \cos x - 5$$ shifts the graph of $$\cos x$$ down by 5 units.
- This means the range shifts from $$[-1, 1]$$ to $$[-1-5, 1-5] = [-6, -4]$$.
4. **Amplitude:**
- Amplitude is the absolute value of the coefficient before $$\cos x$$, which is $$1$$ here.
5. **Period:**
- Since there is no horizontal stretch or compression, the period remains $$360^\circ$$.
**Final answers:**
- Range: $$[-6, -4]$$
- Amplitude: $$1$$
- Period: $$360^\circ$$
