Answer: D) f(n)=8(1.5)^{n-1}


Step-by-step explanation:

From the given table we can see that this is not representing a linear function as the rate of change is not constant.

So it can be exponential growth function A(b)^{n-1},  where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.

Now here at n=1 , f(n)=8

Therefore, A=8

Now, for n=2

f(2)=8(b)^{2-1}\\\Rightarrow12=8b\\\Rightarrow\ b=\frac{12}{8}\\\Rightarrow\ b=1.5

By substitute the values of A and b in the above equation, we get the equation f(n)=8(1.5)^{n-1}

Therefore, the function best shows the relationship between n and f(n) is

f(n)=8(1.5)^{n-1}, where n is the number of weeks.

We are given with the data on teh number of squirrels seen in each week. In this case, the number of squirrels seen increases as week goes. This is a geometric series with a ratio of 1.5 and a1 equal to 8. The equation should be 8 (1.5)^(n-1) where n is the number of weeks. The answer is option D.

What is the formula for the following arithmetic sequence? -9 , -2 , 5 , 12
nirvana33 [79]
First term:  -9
Common difference:  7


a(n) = -9 + 7(n-1), for n = {1, 2, 3, ... }

Check:  what is the first term?  let n=1.   Then a(1) = -9 + 7(1-1) = -9.  
This is correct.

when a relation is drawn on an xy-plane what is another name for the set of all x values from its graph?
Galina-37 [17]

Another name for the set of all x-values for a relation is: domain.

<h3>What is the Domain of a Relation?</h3>

The domain of a relation can be defined as all the x-values that corresponds to the y-values that are plotted on a graph.

They are referred to as the input or the domain of the relation. Therefore, another name for the set of all x-values plotted for a relation on a graph is: domain.
