Answer: In order, the boxes are -9, 1, -9
Step-by-step explanation:
The vertex is the tip point of an absolute value function, which in this case is (-9,1).
The axis of symmetry is a symmetrical line through the fuction which goes through the vertex which would be x = -9.
Find two easy points on a graph and go over however many times you need to rise and how many times to you run.
This simplified is 126x so that is equivalent to this expression
