I think your equation should be f(x) = 10(.5)^x
notice:
10(.5) = 5
5(.5) = 2.5
2.5(.5) = 1.25 <---- not shown, but I multiplied each f(x) value by .5 to
get the next one, so what do you think?
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?
0.5
2
2.5
5
