Use the image to answer the question.

A parabola is graphed on a coordinate plane. The x-axis ranges from negative 2 to 4 in increments of 1. The y-axis ranges from negative 8 to 2 in increments of 1.

Identify the y-intercept and vertex of the parabola.

(1 point)
vertex: (
)

y-intercept: (
)

Incorrect

The vertex is the highest point on the parabola.
The y-intercept is where x equals 0.

Answer 1

To identify the y-intercept and vertex of a parabola from its graph, you need to locate specific points:

1. Y-Intercept: This is the point where the parabola crosses the y-axis, which occurs when \( x = 0 \). Look at the graph and find the corresponding y-coordinate.

2. Vertex: The vertex is the highest or lowest point of the parabola, depending on whether it opens upwards or downwards. Look for the point on the graph where the parabola reaches its maximum or minimum value.

Unfortunately, since I can't see the image, I can't give you the exact coordinates. However, I can guide you on how to find them:

• Locate the point where the parabola crosses the y-axis (for the y-intercept).
• Identify the highest point (if the parabola opens downwards) or the lowest point (if it opens upwards) for the vertex.

Once you have those points, fill in the coordinates in the following format:

• Vertex: (x-coordinate, y-coordinate)
• Y-Intercept: (0, y-coordinate)

If you have the graph data or specific values, please provide them, and I'll help identify the coordinates.
