Transcribed Image Text:**Title: Understanding Trigonometric Graphs**
**Instructions:**
Write an equation of the form \( y = a \sin b x \) or \( y = a \cos b x \) to describe the graph below.
**Graph Explanation:**
- The graph shows a trigonometric wave, specifically a sine or cosine function.
- The x-axis is labeled with multiples of \(\frac{\pi}{3}\), ranging from \(-\frac{4\pi}{3}\) to \(4\pi\).
- The y-axis ranges from -4 to 4, highlighting the amplitude of the wave.
- The wave peaks at approximately 4 and troughs at approximately -4, suggesting an amplitude of 4.
- The wave completes a cycle every \(2\pi\), indicating a period consistent with standard sine and cosine waves.
**Equation Box:**
- Enter the equation in the provided box using the given math symbols: \(\pi\), \(\sin\), \(\cos\), and an equals sign.
**Note:**
Adjust the values of \(a\) and \(b\) in the sine or cosine function to match the amplitude and period observed in the graph.
