The vertex, or minimum, started at (0,0) and moved in the following directions:
1. Left 3 and down 1 to (3,-1)
2. Right 3 and up 1 to (0,0)
3. Left 1 and up 3 to (-1,3)
4. Right 1 and down 3 to (0,0)
Therefore, the vertex, or minimum, ended up back at the starting point of (0,0) after moving in these directions.
How did the vertex, or the minimum, move in this case?left 3 down 1right 3 up 1 left 1 up 3right 1 down 3
