It can be modeled by an exponential function, f(x) is divided by 3 each time x increases by 1.
This means that the base of the exponential function is 1/3, and since the value of f(x) when x=0 is 81, 
I believe the form you mean is
4.8732 x

Well move the decimal point of the 4.8732...7 places to the right.
48,732,000
Now find that answer.
The answer is A.

Answer:
y=x-1
Step-by-step explanation:
Gradient=1
Rise/run=1/1=1
y=x+c
y intercept=-1
y=x-1
305 plus 90= 395. Found by doing 395-90
I honestly don’t know but I hope you find the answer to this question soon and have a good night good luck
