Final answer:
The multiplicative rate of change of a function is determined by the slope of its graph. In the given question, the correct answer would be c) 2.
Step-by-step explanation:
The multiplicative rate of change of a function refers to how the function changes when the input is multiplied by a constant. It is usually represented by the slope of the function's graph. For example, if the function is y = 2x, the multiplicative rate of change is 2 because for every unit increase in x, y increases by 2 units. Therefore, the answer to the given question would be c) 2.
