<u>ANSWER</u>

(0, 1), (1, 3), (2, 9), (3, 27)

<u>EXPLANATION</u>

The first and third options are completely out because the y-value of an exponential function is never zero.

For the second option the y-values has no geometric pattern or common ratio.

For the last option, we can observe the following pattern

1 =  {3}^{0}

{3}^{1}  = 3

{3}^{2}  = 9

{3}^{3}  = 27

:

:

{3}^{x}  = y

The correct choice is the last option

Proximately 32, 800 citizens of the country died in my automobile accident in 2015. Expressed this toll in deaths per day
Anton [14]
Remark
2015 is an odd numbered year. It is not a leap year. It has 365 days in it.

Equation
Total deaths = deaths / day * number of days

Givens
Total deaths = 32800
deaths / day = ???
number of days  = 365

Sub and solve
32800 = x * 365  Divide by sides by 365
32800 / 365 = x
x = 89.86 deaths per day.

Problem
Do you round up, down or leave the number as it is?

I would round up 90 deaths per day. 

Discussion 
Just how much are you out?
Total deaths in a year (rounded) = 90 * 365
Total deaths in a year (rounded)= 32850 which is 50 too many

Suppose you round down 
Total death/day = 89 * 365 = 39485 Rounding up is going to be better if you round at all.

Perhaps you should not round the answer at all and leave it at
89.86 <<<<< answer.
If you have choices, please list them.
