there is a rule for y, in terms of x.
The values for x can be chosen at will.
Usually, as in the table above, the x values are listed in order, from low to high.
can you give me an example? because im not completely following you
hello are you there?
HELLO? You have the table above!
The x values go fro -2 to 2
There is no rule for the x values.
The rule just allows you to figure out a y value for any x value given.

The x values could be anything: -12657, 0, 3,000,000, 3.14159, √2, or whatever.
Then you just need to apply the rule to figure out what y is for each x given.
ok....You dont have to be mean, I just didnt understand im new to this. I just joined a new school and its way ahead from my old one so its hard...
