Post a New 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!

    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)

    Then you will see what a parabola is.

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

    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.
