Which function best models the data?
The table shows the estimated number of bees, y, in a hive x
days after a pesticide is released near the hive.
Bee Population over Time
O y = 9,958(0.972)*
y = 0.972(9,958)*
O y = 9,219x, 150
O y = -150x + 9,219

Ответ:
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.
