look at this graph: what are the coordinates of the vertex? ( )
Answer
Explanation:
Step1: Identify vertex on graph
The vertex of a parabola is the lowest or highest - point. In this upward - opening parabola, it's the lowest point.
Step2: Read x - coordinate
Looking at the x - axis, the x - coordinate of the vertex is 1.
Step3: Read y - coordinate
Looking at the y - axis, the y - coordinate of the vertex is - 8.
Answer:
(1, - 8)
