**Determine the amplitude of the following graph**

The graph provided shows a trigonometric function plotted on the Cartesian plane with the horizontal axis labeled as \( x \) and the vertical axis labeled as \( y \). The curve represents a sinusoidal function (such as a sine or cosine wave).

### Graph Description:
- The function oscillates with alternating peaks and troughs.
- The horizontal \( x \)-axis is marked with intervals ranging from \(-\frac{\pi}{4}\) to \(\frac{3\pi}{4}\), passing through points like \(-\frac{\pi}{8}, 0, \frac{\pi}{8}, \frac{\pi}{4}, \frac{3\pi}{8}, \frac{\pi}{2}\), etc.
- The vertical \( y \)-axis has tick marks running from -5 to 5.

### Key Features of the Graph:
1. **Maximum Value**: The maximum value on the y-axis is 3.
2. **Minimum Value**: The minimum value on the y-axis is -3.

### Amplitude:
- The amplitude of a sine or cosine wave is half the distance between its maximum and minimum values.
- In this graph, the maximum value is \( 3 \) and the minimum value is \( -3 \).
- Therefore, the amplitude \( A \) is calculated as:
  
  \[
  A = \frac{\text{Maximum value} - \text{Minimum value}}{2} = \frac{3 - (-3)}{2} = \frac{6}{2} = 3
  \]

Hence, the amplitude of the given graph is **3**.
