Find the function rule.
x: -2|-1|0 |1 | 2
y: 9|4 |-1|-6|-11
I don't have an answer yet. There's no options, I have to provide an answer. I've been studying this for at least half an hour and I have no idea what it could be. Any help? Thanks.
Look at the changes in x and y
x: up by 1
y: down by 5
so, start with
y = -5x
But, y(0) = -1, not 0, so
y = -5x-1
