Let's analyze the sine function graph you uploaded.

### 1. **Amplitude (A):**
Amplitude is the distance from the midline to the maximum (or minimum) of the wave. From the graph:
- Maximum value: 6
- Minimum value: -6
- Therefore, the amplitude is: 
  \[
  A = \frac{6 - (-6)}{2} = 6
  \]

### 2. **Midline (y):**
The midline is the horizontal line that represents the average of the maximum and minimum values:
- \[
  \text{Midline} = \frac{6 + (-6)}{2} = 0
  \]

Thus, the midline is \( y = 0 \).

### 3. **Period (P):**
The period is the length of one full cycle. In the graph:
- The wave starts at \( x = -7 \) and completes one full cycle at \( x = 1 \).
- The distance between these points is:
  \[
  P = 1 - (-7) = 8
  \]
  
### 4. **Equation of the sine function:**
The general form of the sine function is:
\[
y = A \cdot \sin\left(\frac{2\pi}{P} \cdot (x - D)\right) + C
\]
where:
- \( A = 6 \) (amplitude)
- \( P = 8 \) (period)
- \( C = 0 \) (midline)
- \( D \) represents a phase shift, but since the sine wave starts at the origin, we don't need a shift (\( D = 0 \)).

Thus, the equation is:
\[
y = 6 \cdot \sin\left(\frac{2\pi}{8} \cdot x\right) = 6 \cdot \sin\left(\frac{\pi}{4} \cdot x\right)
\]

### Relative Questions:
1. What happens if we change the amplitude of a sine wave?
2. How would the graph shift if there was a phase shift \( D \)?
3. What is the relationship between the period and frequency of a sine wave?
4. How can we modify the sine equation to represent a cosine function instead?
5. What real-world phenomena can be modeled using sinusoidal functions?

### Tip:
When identifying the period of a sine function from a graph, locate two consecutive peaks (or troughs) and measure the distance between them.
