## Determine the Period of the Following Graph

To determine the period of a trigonometric graph, you need to identify the length of one complete cycle of the graph along the x-axis. 

### Analysis of the Graph

The graph provided is a sinusoidal wave. The y-axis ranges from -5 to 5, and the x-axis is marked from -2π to 3π, with increments of π/2.

### Observations

1. The graph starts at -2π on the left, reaches a minimum at -π, goes to a maximum at π, and then continues the pattern.
2. The starting point of the graph (peaks/valleys) repeats after a specific interval along the x-axis.

### Determining the Period

- From minimum at -π to maximum at π, we cover one complete cycle, as the pattern repeats itself after π/2 to 2π interval.
- The period here is thus the distance between two repeating points along the x-axis.

**Conclusion:** The period of this sinusoidal graph is 2π.

Note: Always ensure to compare the graph's repeating cycles to properly confirm the periodic interval.

### Graph Summary

- **Axis Labels:** 
  - x-axis ranges from -2π to 3π.
  - y-axis ranges from -5 to 5.
- **Periodic Nature:** 
  - The pattern reiterates every 2π units along the x-axis.
  
Understanding the period helps comprehend the behavior of trigonometric functions, which is essential in various applications in mathematics, physics, and engineering.
