which function has the greater rate of change?

Question

x-axix: -1 | 0 | 1 | 2 |
y-axis: 0 | 1 | 2 | 3 |

the graph has a line and 3 dots on the line. the first dot is 0, -1
the second dot is 0, 1
the third dot is 1, 2

A. the rates of change are equal
B. the graph has a greater rate of change
C. the table has a greater rate of change
D. none of the above

I say it's either A or C

Answer 1

I only see one function:

f(x) is (-1,0),(0,1),(1,2),(2,3)

x and y change at the same rate. When x increases by 1, so does y.
