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.
