What are the coordinates of the vertex of the graph or table? Is it a maximum or minimum?
X Y
0 1
–1 –2
–2 –3
–3 –2
–4 1
To find the vertex of the graph or table, we need to locate the point where the y-value reaches a maximum or minimum.
Looking at the 'Y' column, we can see that the y-values increase from -3, reach a maximum at 1, and then decrease again. Therefore, the highest y-value is 1, and it occurs at x = -4.
So, the vertex of the graph or table is (-4, 1), and it represents a maximum.
