Answer:

y = 9,958(0.972)^t

Step-by-step explanation:

From point to point, the difference in days is always constant (10 days), but the difference between estimated number of bees is not constant.

10000  - 7500  = 2500

7500  - 5600  = 1900

5600  - 4200  = 1600

4200  - 3200  = 1000

3200  - 2400 = 800

Therefore, the data don't fit a line.

From the other two options:

y = 9,958(0.972)^t

y = 0.972(9,958)^t

only the first one has sense, because its initial amount of bees is 9,958 (near to 10,000) and in the second option is 0.972.

Answer:

y=9,958(0.972)^x...................
