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) = 3x + 15
f(x) = 12
Please give explanation and answer!!

I think it’s A “ f(x) = -3x + 12” because your going down so it’s a negative

Solved:
A -3x/ +3 12 +3 means x=15

Now B is 3x/ -3 15 -3 means x = 12

I don’t think C is the answer at all I think it’s A but I’m not 100% sure
XD I hope my answer helps you one way or another
