Solve graphically.


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?

  • Algebra -

    For the second equation just graph the points I gave you
    (-3 9)

  • Algebra -

    Then you will see what a parabola is.

  • Quick question -

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

  • Algebra -

    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.
