Answer:
Function B has the greater rate of change.
Step-by-step explanation:
Given the functions in the attached image;
The rate of change of function A is equal to the slope of the line;

The rate of change of the Function B is equal to the slope of the function;

From the derived rate of change, we can see that the rate of change of the function B is more than that of Function A.

Therefore, Function B has the greater rate of change.
