Final answer:
The functions that have an additive rate of change of 3 are 4 and 2.
Step-by-step explanation:
The functions that have an additive rate of change of 3 are:
- A. 4
- D. 2
For a function to have an additive rate of change of 3, it means that the function increases by 3 units for every unit increase in the independent variable. So, if the independent variable increases by 1 unit, the function will increase by 3 units.
