You lost me at the title.
It has been far too many years since I've had to do math that involved letters of any kind.

Though, now that I look at the equation, it is starting to come back to me......
let's see, plug in the following nubmers for x to solve the equation:
-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Use the answers to plot the graph

How am I doing so far?

Now, domain and image set....
would the domain be the range of points plotted?
I don't remember ever hearing the term 'image set'.
And WTF are they talking about rules for?

Yup, you lost me.

Edit: don't let psych majors help you with your math. They (and by they, I have to include me) only have a small handfull of equations they use to analyze research data.......but mostly they just use the ANOVA equation and pretend no other math exists. Sorry. I really felt like I was understanding your math there for a few minutes. I'll just go feel stupid in the corner over there.....
