Question

name the vertex. 5

Explanation:

Step1: Identify the vertex

The vertex of a parabola is its highest or lowest point. For this downward - opening parabola, we look for the point where the parabola changes direction.
Looking at the graph, we can see that the vertex is at the point where \(x=- 1\) (by looking at the horizontal grid lines) and \(y = 4\) (by looking at the vertical grid lines).

Answer:

\((-1,4)\)
