The curve through the ordered pairs (0, 10), (1, 5), and (2, 2.5) can be represented by the function f(x) = 10(0.5)x. what is the multiplicative rate of change of the function?
a. 0.5
b. 2
c. 2.5
d. 5.

The answer is A.

To solve this question, look at the y coordinates. To get from 10 to 5, and from 5 to 2.5, you divide them by 2. In other words, you multiply them by .5. So, the multiplicative rate will be .5.
