The graph you uploaded shows a periodic function, likely a sine or cosine wave. Here's a detailed analysis based on the image:

• Amplitude: The graph reaches a maximum height of 5 and a minimum of -5, so the amplitude is $5$.
• Period: The graph completes a full cycle between $-\pi$ and $2\pi$, so the period of the function is $2\pi$. This suggests no horizontal stretching.
• Vertical Shift: The midline is along the x-axis, indicating no vertical shift.
• Phase Shift: The graph does not appear to be horizontally shifted since it crosses the origin, matching the shape of a standard sine function.
• Equation: Based on the amplitude and the lack of any shift, the equation of this graph is likely: $y = 5 \sin(x)$

It could also represent a cosine function, $y = 5 \cos(x)$, with an appropriate phase shift.

Would you like more details or clarification?

Here are 5 related questions for practice:

1. How would the equation change if the amplitude were doubled?
2. What would happen to the graph if the period was halved?
3. How can you determine the function’s frequency from its period?
4. How does a vertical shift affect the equation of a sine or cosine wave?
5. What would a phase shift of $\frac{\pi}{4}$ look like on this graph?

Tip: When analyzing sine or cosine graphs, remember that the amplitude affects the height, while the period controls the width of the cycles.
