Answer:
Family a because it is more chronological
Step-by-step explanation:
I wanna say 10 or ether -10 since if it was subtracted from 2 then it would equal -8
Your answer can only be simplified to
256x^10 - 384^8 - 448^6
First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry
1st: group the number
(X2+6x)-9
2nd: use b/2
6/2 = 3 , 3^2= 9
(X2+6x+9)-9-9
(X2 + 3)-18
Vertex is 3,-18 so the symmetry is 3
