It seems that I am unable to generate a graph at this moment. However, I can describe how to graph the function \( f(x) = 4 \cot x \) for two periods. ### Steps to Graph \( f(x) = 4 \cot x \): 1. **Identify Key Points**: - The cotangent function has vertical asymptotes where \( \cot x \) is undefined, which occurs at \( x = n\pi \) for \( n \in \mathbb{Z} \). For the interval \( [0, 2\pi] \), the asymptotes are at \( x = 0 \), \( x = \pi \), and \( x = 2\pi \). - The function crosses the x-axis at \( x = \frac{\pi}{2} \) and \( x = \frac{3\pi}{2} \). 2. **Plot the Asymptotes**: - Draw vertical dashed lines at \( x = 0 \), \( x = \pi \), and \( x = 2\pi \). 3. **Plot the Key Points**: - At \( x = \frac{\pi}{2} \), \( f\left(\frac{\pi}{2}\right) = 4 \cot\left(\frac{\pi}{2}\right) = 0 \). - At \( x = \frac{3\pi}{2} \), \( f\left(\frac{3\pi}{2}\right) = 4 \cot\left(\frac{3\pi}{2}\right) = 0 \). 4. **Behavior Near Asymptotes**: - As \( x \) approaches \( 0 \) from the right, \( f(x) \) approaches \( +\infty \). - As \( x \) approaches \( 0 \) from the left, \( f(x) \) approaches \( -\infty \). - As \( x \) approaches \( \pi \) from the left, \( f(x) \) approaches \( +\infty \). - As \( x \) approaches \( \pi \) from the right, \( f(x) \) approaches \( -\infty \). - The same behavior occurs at \( x = 2\pi \). 5. **Sketch the Curve**: - Connect the points smoothly, ensuring the curve approaches the asymptotes and crosses the x-axis at the identified points. ### Summary of Results: - **Stretching Factor**: \( 4 \) - **Phase Shift**: \( 0 \) If you have graphing software or a graphing calculator, you can input the function \( f(x) = 4 \cot x \) to visualize it accurately.
