graph y=sin(1/2x+pi/6) and choose an appropriate starting graph 

To graph the function \( y = \sin\left(\frac{1}{2}x + \frac{\pi}{6}\right) \), let's break down the important elements and then proceed with graphing.

### 1. **Base Function**:
The base function is \( \sin(x) \), which is a periodic function with a period of \( 2\pi \) and amplitude 1. The sine function oscillates between -1 and 1.

### 2. **Horizontal Stretching**:
The coefficient \( \frac{1}{2} \) inside the sine function causes a horizontal stretch. Normally, the period of \( \sin(x) \) is \( 2\pi \). To find the new period, we divide the standard period by the coefficient of \( x \):
\[
\text{New Period} = \frac{2\pi}{\frac{1}{2}} = 4\pi
\]
This means the graph will take twice as long to complete one full cycle.

### 3. **Horizontal Shift**:
The \( + \frac{\pi}{6} \) inside the function causes a horizontal shift. To determine the shift, we solve:
\[
x = -\frac{\pi}{6}
\]
This indicates that the entire graph is shifted to the left by \( \frac{\pi}{6} \).

### 4. **Amplitude**:
The amplitude is not affected by any coefficient outside the sine function, so it remains 1 (the graph oscillates between -1 and 1).

### **Step-by-Step Graphing**:
1. **Start with \( y = \sin(x) \)**, as the base graph.
2. **Apply the horizontal stretch**: Compress the graph horizontally so that the period becomes \( 4\pi \).
3. **Apply the horizontal shift**: Shift the entire graph to the left by \( \frac{\pi}{6} \).
4. The amplitude remains 1, so the graph oscillates between -1 and 1.

### Appropriate Starting Graph:
A good starting graph would be \( y = \sin(x) \), then apply the stretch and shift as described above. The graph will complete one full period between \( x = -\frac{\pi}{6} \) and \( x = \frac{11\pi}{6} \).
