Answer:
"4" represents that there are 4 rabbit in the beginning.
Step-by-step explanation:
Given that the population of a species of rabbit triples every year. This
can be modeled by function
and
.
Now we need to find about what does the 4 represent in the given function.
We know that exponential function is given by
. Where "a" represents the initial amount.
we have a=4 in given function
.
So that means "4" represents that there are 4 rabbit in the beginning.
Answer:

Step-by-step explanation:
Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be 
Because the sequence multiplies by 3 each time, The base number in that equation would be
.
So
of the equation would be:
.
Compare the 2 equations:
4, 12, 36
3, 9 ,27
The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is:
.
Combine these 2 equations together and you get:
.
P=7+7+12+12P=14+24P=38
