To determine the symmetry of the graph, check each axis:
- **\( y \)-axis**: Replace \( x \) with \( -x \). If the equation remains the same, it's symmetric about the \( y \)-axis.
- **\( x \)-axis**: Replace \( y \) with \( -y \). If the equation remains the same, it's symmetric about the \( x \)-axis.
- **Origin**: Replace both \( x \) with \( -x \) and \( y \) with \( -y \). If the equation remains the same, it's symmetric about the origin.
Choose the correct option based on which symmetry condition is satisfied.
**Answer:**
- **A. \( x \)-axis**
- **B. \( y \)-axis**
- **C. Origin**
- **D. Both \( x \)-axis and \( y \)-axis**
If the graph is symmetric about the \( y \)-axis, select **B. \( y \)-axis**.

I'm unable to view the graph you're referring to, but I can help you determine symmetry based on the general principles. Here's how you can check for different types of symmetry in a graph:
1. **Symmetry with respect to the \( y \)-axis**:
- **Test**: Replace \( x \) with \( -x \) in the equation of the graph.
- **If the equation remains unchanged**, the graph is symmetric about the \( y \)-axis.
- **Example**: The equation \( y = x^2 \) is symmetric about the \( y \)-axis.
2. **Symmetry with respect to the \( x \)-axis**:
- **Test**: Replace \( y \) with \( -y \) in the equation of the graph.
- **If the equation remains unchanged**, the graph is symmetric about the \( x \)-axis.
- **Note**: Most functions do not have \( x \)-axis symmetry because this would imply they are not functions (they would fail the vertical line test).
3. **Symmetry with respect to the origin**:
- **Test**: Replace both \( x \) with \( -x \) and \( y \) with \( -y \) in the equation of the graph.
- **If the equation remains unchanged**, the graph is symmetric about the origin.
- **Example**: The equation \( y = x^3 \) is symmetric about the origin.
4. **Symmetry with respect to both the \( x \)-axis and the \( y \)-axis**:
- **Condition**: The graph must satisfy both the \( x \)-axis and \( y \)-axis symmetry conditions individually.
- **Example**: The equation \( y^2 = x^2 \) (which represents two lines, \( y = x \) and \( y = -x \)) is symmetric about both axes.
**How to Choose the Correct Answer:**
- **A. \( x \)-axis**: If only the \( x \)-axis symmetry condition is satisfied.
- **B. \( y \)-axis**: If only the \( y \)-axis symmetry condition is satisfied.
- **C. Origin**: If only the origin symmetry condition is satisfied.
- **D. Both \( x \)-axis and \( y \)-axis**: If both the \( x \)-axis and \( y \)-axis symmetries are satisfied.
**Example Application:**
Suppose you're given the graph of \( y = x^2 \).
- Replace \( x \) with \( -x \): \( y = (-x)^2 = x^2 \) (unchanged) → Symmetric about the \( y \)-axis.
- Replace \( y \) with \( -y \): \( -y = x^2 \) → Not the same as the original equation → Not symmetric about the \( x \)-axis.
- Replace both \( x \) with \( -x \) and \( y \) with \( -y \): \( -y = (-x)^2 = x^2 \) → Not the same as the original equation → Not symmetric about the origin.
**Conclusion for the Example:** The graph is symmetric with respect to the \( y \)-axis. Therefore, the correct answer would be **B. \( y \)-axis**.
If you can provide more details about the graph or its equation, I'd be happy to help you determine its symmetry more specifically!
