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.

Answer 1

To identify the y-intercept and vertex of a parabola from a graph, you would typically look for the following:

1. Y-Intercept: This is the point where the graph crosses the y-axis. In terms of coordinates, this point will be of the form (0, y).

2. Vertex: This is the highest or lowest point of the parabola, depending on its orientation (opening upwards or downwards). The vertex coordinates will be in the form (h, k), where 'h' is the x-coordinate and 'k' is the y-coordinate.

Since I cannot see the graph you're referring to, here's what you can do:

• Look at where the parabola crosses the y-axis to find the y-intercept (note the y-coordinate when x=0).
• Identify the highest or lowest point of the parabola to find the vertex (note both the x and y coordinates).

Once you've determined those values from the graph, write them down in the specified format:

• Vertex: (h, k)
• Y-Intercept: (0, y)

If you provide specific points from the graph, I can help clarify further!
