Answer:

5

Explanation:

For an exponential function of the form ...

f(x) = a·b^x

the "multiplicative rate of change" or "growth factor" is the base of the exponential term: b.

Comparing this form to your function, we see that ...

f(x) = 2·5^x

a = 2, b = 5

The multiplicative rate of change is 5.
