Answer 5

i don't thing my average rate of change should be this high

Answer 6

When it asks for "average rate of change" it usually gives you a starting point and an ending point. But it only gave you one point, the twelfth month. Are you sure it doesn't ask "what is the average rate of change over the 12 months?" ie, from t = 0 to t = 12?

Answer 7

wait let me post the snap shot of the original thing

Answer 9

did it halp?!?!?!?!

Answer 10

so it sounds like they want you to find the average rate of change from month t = 11 to t = 13?
or maybe from t = 12 to t = 13?
or maybe from t = 11 to t = 12?

it's not exactly clear what they want for part (a)

Answer 11

yeah i think it's from 11th to 12th month..

Answer 12

and as for your equation, I would use

\[\Large P = A*(2)^t\]

where
P = population after t months
A = initial population (in this case 14)
t = time in months

Answer 13

`yeah i think it's from 11th to 12th month..`
ok compute \[\Large \frac{P(12)-P(11)}{12-11}\]
using the function
\[\Large P(t) = 14*(2)^t\]
