The function f(x) = 2 • 5x can be used to represent the curve through the points (1, 10), (2, 50), and (3, 250). what is the multiplicative rate of change of the function?

The multiplicative rate of change of the function is:

                                5

We are given a function f(x) in terms of the variable x as:

The function passes through:

                 (1, 10), (2, 50), and (3, 250).

We know that the multiplicative rate of change of the exponential function :

is b.

Here we have:   a=2 and b=5

(i.e. there is a multiplication by a fixed number i.e. 5 as compared to the preceding value )

  Hence, the multiplicative rate of change is:

                             5
