To determine equations for graphs 6 and 7, let's analyze the features of each graph.

### Graph 6:
Observing graph 6, the graph shows a sine or cosine function with high frequency, meaning it oscillates rapidly within the interval \(-2\pi\) to \(2\pi\). This indicates a trigonometric function with a small period, suggesting a larger frequency (high \(b\) value in \(y = a \sin(bx)\) or \(y = a \cos(bx)\)).

Key observations:
- **Amplitude**: The oscillations reach approximately \(\pm 2\), so the amplitude \(a \approx 2\).
- **Frequency**: There are roughly 6 full oscillations between \(-2\pi\) and \(2\pi\), implying \(b \approx 3\).
- **Equation form**: Given these parameters, the function resembles \(y = 2 \sin(3x)\) or \(y = 2 \cos(3x)\).

**Equation for Graph 6**:
\[
y = 2 \sin(3x)
\]
or equivalently,
\[
y = 2 \cos(3x)
\]

### Graph 7:
Graph 7 appears to have a sine or cosine function with a smaller frequency and larger amplitude, oscillating more gradually than graph 6.

Key observations:
- **Amplitude**: The peaks are around \(\pm 3\), so \(a \approx 3\).
- **Frequency**: It completes about 1.5 cycles between \(-2\pi\) and \(2\pi\), suggesting \(b \approx \frac{3}{2}\).
- **Equation form**: This graph likely corresponds to \(y = 3 \sin\left(\frac{3}{2}x\right)\) or \(y = 3 \cos\left(\frac{3}{2}x\right)\).

**Equation for Graph 7**:
\[
y = 3 \sin\left(\frac{3}{2}x\right)
\]
or equivalently,
\[
y = 3 \cos\left(\frac{3}{2}x\right)
\]

### Additional Questions
1. How do we determine the amplitude and frequency from a trigonometric graph?
2. What is the impact of the coefficient \(b\) on the period of a trigonometric function?
3. How do sine and cosine graphs differ visually if they have the same amplitude and frequency?
4. Can we convert between sine and cosine equations for the same graph?
5. How do phase shifts affect the equation of a sine or cosine graph?

### Tip:
For trigonometric functions, remember that the period is calculated as \( \frac{2\pi}{|b|} \), where \(b\) is the frequency coefficient in the function.
