What is the multiplicative rate of change for the exponential function f(x)=2 (5/2)-x

The multiplicative rate of change is

Step-by-step explanation:

Here, the given function,

Which is an exponential function,

Since, in an exponential function

b is called growth factor or  multiplicative rate of change,

By comparing,

b = 2/5,

Hence, The multiplicative rate of change of the given function is

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
