    Are you to rearrange the equation so that "y" is by itself?

    If so, subtract x^2 from both sides. Then divide both sides by 9. Afterwards, find the square root. Simple algebra.

    Looks about it. Is everything on the right side divided by 9? Or just whats in the square root?

    I'm still iffy on whether or not this is what's required for this question.

    y as a function of x: y(x) =
