Answer:
first step is to put the (x-9)^2 into a standard form which is y=x^2−18x+81 then choose two integers larger than the x-value of the vertex point.next choose two integers smaller than the x-value of the vertex point. lastly substitute these values in place of "x" in the equation and solve for "y".
Step-by-step explanation:
x | y
7 | 4
8 | 1
9 | 0
10 | 1
11 | 4
4=(11-9)^2
1=(10-9)^2
0=(9-9)^2
1=(8-9)^2
4=(7-9)^2
