look at this graph:\nwhat are the coordinates of the vertex?
Answer
Explanation:
Step1: Identify the vertex
The vertex of a parabola is the lowest (or highest) point. For this upward - opening parabola, we look at the point where the parabola changes direction.
Step2: Determine the coordinates
Looking at the graph, the parabola is symmetric about the y - axis (since it opens up and is centered on the y - axis). The x - coordinate of the vertex is 0 (because it lies on the y - axis). The y - coordinate can be seen from the graph; the vertex is at (0, - 10) (by looking at the grid and the position of the lowest point of the parabola).
Answer:
(0, - 10)
