Answer:
The numbers missing (in order) are:
27, 9, 1/9 and 1/27
The correct answer is c.
Explanation:
We can find these numbers by plugging them into the equation one at a time. An example is done for you.
y = (1/3)^x
y = (1/3)^-3
y = 1/(1/3)^3
y = 1/(1/27)
y = 27
After we do this for each, we can graph them and see that the numbers are getting lower from left to right.
