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 this case we have a function of the form:
 [tex]f (x) = 2 * 5 ^ x [/tex]
 We will evaluate the function for different values of x:

 For x = 1:
 [tex]f (1) = 2 * 5 ^ 1 = 2 * 5 = 10 [/tex]

 For x = 2:
 [tex]f (2) = 2 * 5 ^ 2 = 2 * 25 = 50 [/tex]

 For x = 3:
 [tex]f (3) = 2 * 5 ^ 3 = 2 * 125 = 250 [/tex]

 We note that for each value of x, the function is 5 times greater than the previous value.
 
 Answer:
 The multiplicative rate of change of the function is:
 5
 The function is 5 times greater for each value of x.
