### Analyzing Sinusoidal Functions

#### Graph Analysis:
The graph provided represents a sinusoidal function, which is characterized by its wave-like oscillations. We will analyze this graph to determine the amplitude, period, midline, and equation of the function.

#### Steps for Analysis:

1. **Amplitude**: 
   - The amplitude is the distance from the midline to the maximum or minimum value of the function.
   - From the graph, determine the highest and lowest points that the function reaches.

2. **Period**:
   - The period is the distance (along the x-axis) it takes for the function to complete one full cycle.
   - Identify the points where the function starts repeating its pattern.

3. **Midline**:
   - The midline is the horizontal line that lies halfway between the maximum and minimum values of the function.
   - It can be found by averaging the maximum and minimum values.

4. **Function Equation**:
   - The standard form of a sinusoidal function is \( f(x) = a \sin(b(x - c)) + d \) or \( f(x) = a \cos(b(x - c)) + d \).
   - Where \( a \) is the amplitude, \( b \) affects the period, \( c \) is the phase shift, and \( d \) is the midline.

#### Graph Insights:

- The function reaches its maximum at \( y = 3 \) and minimum at \( y = -9 \).
- Thus, the amplitude \( a \) is \( \frac{(3 - (-9))}{2} = \frac{12}{2} = 6 \).
- The midline \( d \) is \( \frac{(3 + (-9))}{2} = \frac{-6}{2} = -3 \).

- From the graph, one full cycle appears to span 6 units along the x-axis, indicating the period \( T \).
  - The period formula for a sinusoidal function is \( T = \frac{2\pi}{b} \).
  - If the period \( T \) is 6, then \( b = \frac{2\pi}{6} = \frac{\pi}{3} \).

Based on the shape and starting points, the function can be modeled by a cosine or sine function. Assuming no phase shift, the function \( f(x) \) is
