Question

Solve graphically.

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!

Answer 1

For the second equation just graph the points I gave you
(-3 9)
(-2,4)
(-1,1)
(0,0)
(1,1)
(2,4)
(3,9)

Answer 2

Then you will see what a parabola is.

Answer 3

Just so I can know in the future, how exactly did you figure those points out?
Thanks!

Answer 4

I just put in some values of x and calculated y. Of course I had the advantage of knowing what the curve would look like.
