### Exercise: Graph of \( f(x) = \cot(x) + 1 \)

#### Instructions:
1. **Draw asymptotes as dashed lines on graph.**

2. **Amplitude:**  
   (Leave blank, as cotangent functions do not have an amplitude).
   
3. **Period:**  
   \( 0 < Bx - C < \pi \)  
   \( \_\_\_\_ < x < \_\_\_\_\_ \) (Fill in the blank intervals).

4. **Domain:**  
   All real numbers except every \_\_\_\_ (period), beginning at \_\_\_\_.
   
5. **Vertical shift:**  
   (Leave blank, no vertical shift for this function).

6. **Asymptotes:**  
   \( x = \_\_\_\_\_, x = \_\_\_\_\_ \) (Identify the vertical asymptotes for one period).

7. **Point of inflection:**  
   \(( \_\_\_\_\_, \_\_\_\_\_ )\) (Identify if exists).

8. **1/4 and 3/4 points:**  
   \(( \_\_\_\_\_, \_\_\_\_\_ )\) and \(( \_\_\_\_\_, \_\_\_\_\_ )\) (Mark these points on the graph).

9. **Range:**  
   \(\_\_\_\_\_\_\_) (Define the range of the function).

10. **Graph two periods of the curve. Draw the asymptotes as dashed lines.**

#### Graph Description:
The provided graph shows the \(y\)-axis in the vertical direction and the \(x\)-axis in the horizontal direction. The x-values range from \(-\pi\) to \(2\pi\), and y-values range from \(-3\) to \(4\). Dashed vertical lines indicate the asymptotes where the function is undefined. Points are marked on the curve at regular intervals.

Key points to include:
- Vertical asymptotes at \( x = 0 \), \( x = \pi \), \( x = 2\pi \), etc.
- Increasing behavior of the function \( f(x) \) within each period \((0, \pi)\) and \((\pi, 2\pi)\).
- The function values transition smoothly through the points marked on the graph.
