Consider the two functions shown here. Which function has the greater rate of change? Explain your answer.

Responses
A Function 1, because its rate of change is 2.Function 1, because its rate of change is 2.
B Function 2, because its rate of change is ½.Function 2, because its rate of change is ½.
C Function 2, because its rate of change is 7.Function 2, because its rate of change is 7.
D Function 1, because its rate of change is ½ .

The question does not provide the functions or their equations, so it is impossible to determine the rates of change or compare them.
