Also use graph to determine domain and range
**Topic: Graphing Trigonometric Functions**

**Graph the following function:**

Show at least two cycles. Use the graph to determine the domain and range of the function.

\[ y = \csc \left( \frac{2\pi}{3} x \right) + 1 \]

**Choose the correct graph below.**

- **Option A:** This graph shows vertical asymptotes and csc function waves, ranging from \( -5 \) to \( 5 \), displaying two cycles.
  
- **Option B:** This graph displays the csc function with vertical asymptotes and the wave structure is shifted up, ranging from \( -2 \) to \( 5 \) and horizontally scaled, covering \( -2\pi \) to \( 2\pi \). 

- **Option C:** This graph displays the csc function with vertical asymptotes and wave structure not appearing to match the given function scaling, ranging evenly along both axes.

- **Option D:** This graph displays the csc function correctly reflecting \( y = \csc \left( \frac{2\pi}{3}x \right) + 1 \). It shows accurate vertical asymptotes and the wave structure fitting both the periodicity and vertical shift. It ranges from \( -3 \) to \( 5 \).

**Use the graph to determine the domain of:** 

\[ y = \csc \left( \frac{2\pi}{3} x \right) + 1 \]

**Explanation of Graph (Option D):**
1. **Vertical Asymptotes:** These occur at \( x = \frac{3}{2}k\pi \) where \( k \) is an integer. The function has vertical asymptotes whenever \( \sin \left( \frac{2\pi}{3} x \right) = 0 \), which happens at \( \frac{2\pi}{3} x = k\pi \), resulting in \( x = \frac{3k}{2} \).

2. **Range of Function:** The range of the function \( y = \csc \left( \frac{2\pi}{3} x \right) + 1 \) is \( (-\infty, 0) \cup (2, \infty) \).

3. **Vertical Shift:** The \( +1 \) indicates an
