Answer 1

Function A has a smaller rate of change than Function B.

If you input the same x values that have been recorded for Function B into Function A than you can compare the rates of change.

4(1) - 7 = -3

4(2) - 7 = 1

4(3) - 7 = 5

4(4) - 7 = 9

The values increase by 4 each time but in Function B they increase by 5. Therefore Function A has a smaller rate of change.
