a)
so, if the population doubled in 5 years, that means t = 5. So say, if we use an amount for "i" or P in your case, to be 1, then after 5 years it'd be 2, and thus i = 1 and A = 2, let's find "r" or "k" in your equation.


b)
A = 10,000, t = 3
Answer:
The answer is "It has the same domain as the function f(x) = --x".
Step-by-step explanation:
If we consider its parent function that is: y= x
Domain function is:
The range function is: 
The function has both the same (domain and range).
Answer:
10 ft.
Step-by-step explanation:
8.8 ÷ 4= 2.2
22÷2.2= 10
X can be 3 because:
(3+1)(3)=(4)(3)=12
I believe that is the only possible value for x.
Good luck to you!
