Question

Examine the following input-output table that contains some ordered pairs of a sequence.

n f(n)
1 9
2 6
3 3
4 0

The sequence can be represented as a function if the domain is the natural numbers.

Which explicit formula in function notation describes this sequence?

A.) f(n)=12x+3
B.) f(n)=3x+12
C.) f(n)=3x−12
D.) f(n)=−3x+12

Answer 1

hey mate

here is your answer...

Answer:

the relation which relates the each element of the first to second is

-3x+12.

you see,

when n=1

then

f(1)=-3*1+12

=9

when n=2

f(2)=6

when n=3

f(3)=3

and when n=4

f(4)=0.
