x-y=0

y=x²

The reason I don't understand the question is the second equation with the x². How do I graph that? I'm not sure if I ever graphed with an exponent, and if I did, it was a long time ago.

I'm reposting this because I didn't understand Damon's answer (I don't know what a parabola is) and I doubt anyone would look down again that far. Could you explain it in more simple terms?

Thanks!

**Damon**, Thursday, February 19, 2009 at 6:22pmFor the second equation just graph the points I gave you

(-3 9)

(-2,4)

(-1,1)

(0,0)

(1,1)

(2,4)

(3,9)

**Tessa**, Thursday, February 19, 2009 at 6:32pmJust so I can know in the future, how exactly did you figure those points out?

Thanks!

**Damon**, Thursday, February 19, 2009 at 10:19pmI just put in some values of x and calculated y. Of course I had the advantage of knowing what the curve would look like.
