I need some help on this function rule question please.
8.) Find the function rule.
x: -2 -1 0 1 2
y: 9 4 -1 -6 -11
I'm having a really hard time figuring this out. Thanks to anyone that helps:)
Note that y decreases by 5 when x increases by 1. So, start with
y = -5x
Now note that y(0) = -1, so you need to adjust the function a bit:
y = -5x-1
