Answer:
The answer is 5.
Step-by-step explanation:
Multiplicative rate of change can be described as the rate change based on a original amount or point.
If we look at the given points for the function f(x) = 2.5x, we can see that the x coordinates increase by one while the y coordinate is increasing by 5 times it's value for the previous point.
So we can say that the multiplicative rate of change is 5 for the function f(x) = 2.5x.
