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?

For an exponential function written as f(x) = a·b^x, the multiplicative rate of change is the base, b. Here f(x) = 2·5^x, so each time x increases by 1, the function value is multiplied by 5 (10 to 50, then 50 to 250). The multiplicative rate of change is 5.
