a) Function A (table): rate of change = 2.5/1 = 2.5
Function B (graph): rate of change= -4/1 = -4
You should use change in y over change in x for the table
For the graph: move 4 down to get to the center (0,0) =-4 and then the same for -1 to 0
b) Function A should have a greater rate of change
**I hope this is right!
