Given the sequence 12, 9, 6, 3, ... where x = 0, 1, 2 ...,

what is the function rule?

f (x) = - 3

f (x) = - 3x + 12

f (x) = 12

f (x) = 3x + 15

f (x) = - 3x + 12

Step-by-step explanation:

The chart could be represented like this:

x y

0 12

1 9

2 6

3 3

Suppose that f (x) = y

And substitute x values.

y = - 3x + 12

"x = 0"

y = - 3 (0) + 12

y = 0 + 12

y = 12

"x = 3"

y = - 3 (3) + 12

y = - 9 + 12

y = 3

From the results, it corresponds to the function.
