**Understanding Graphs of Mathematical Functions**

On this educational page, we will explore and analyze two different graphs typically encountered in trigonometry and linear algebra.

### Graph 1: Sine Wave
The first graph represents the function \( f(x) = \sin(x) \). This sine wave is a fundamental concept in trigonometry and depicts periodic oscillation. Key features of the sine wave include:

- **Periodicity**: The graph repeats every \( 2\pi \) units along the x-axis.
- **Amplitude**: The maximum and minimum values of the sine function are 1 and -1 respectively, indicating the amplitude of oscillation.
- **Zero Crossings**: The function crosses the x-axis at integer multiples of \( \pi \), where the sine value is zero.
- **Symmetry**: The graph is symmetric about the origin, indicating it is an odd function, i.e., \( \sin(-x) = -\sin(x) \).

### Graph 2: Constant Function
The second graph shows a horizontal line, representing a constant function \( g(x) = k \) where \( k \) is a constant. In this particular graph:

- **Consistency**: The value of \( k \) depicted is 0, hence the function is \( g(x) = 0 \).
- **Horizontal Line**: This line runs parallel to the x-axis and indicates that for every value of \( x \), \( g(x) \) remains equal to 0.
- **Zero Slope**: Since it is a constant function, its slope is zero, representing no change over the x-axis.

These fundamental graphs provide the groundwork for more complex mathematical analysis and are essential for both theoretical understanding and practical applications in various fields of science and engineering.

**Title: Identifying Functions from Graphs**

**Objective**: Learn how to determine if a graph represents \( y \) as a function of \( x \).

**Instructions**: Select all the following graphs which represent \( y \) as a function of \( x \).

### Graph Analysis:

1. **Graph 1**: A straight line extending from the bottom left to the top right of the graph.
   - **Description**: The graph passes the vertical line test, as any vertical line would only intersect the curve at one point.
   - **Function?**: Yes.
   
2. **Graph 2**: A circle centered at (-1, 1) with a radius of 2.
   - **Description**: The graph fails the vertical line test, as some vertical lines will intersect the circle at two points.
   - **Function?**: No.

3. **Graph 3**: A polynomial curve resembling an "N" shape, starting from the bottom left, rising, then dipping, and finally rising steeply to the top.
   - **Description**: The graph passes the vertical line test, as any vertical line would only intersect the curve at one point.
   - **Function?**: Yes.

4. **Graph 4**: A complex wave-like curve with multiple peaks and valleys.
   - **Description**: The graph fails the vertical line test in some regions as some vertical lines intersect the curve at multiple points.
   - **Function?**: No.

### Conclusion:

Based on the vertical line test, **Graphs 1 and 3** represent \( y \) as a function of \( x \).
