    And the equation of a circle is (x−h)^2+(y−k)^2=r^2

    So all you have to do is plug in the #'s and simplify

    So its x^2 +(y+2)^2=9?

    (x - 0)^2 + (y + 2)^2 = 9

    But it is not a circle so there might be a different function

    @taylorz115820 is correct - it is NOT a circle but an ellipse instead. The general equation is (x-x0)^2/a^2 + (y-y0)^2/b^2 = 1 Please read the below for details: http://mathworld.wolfram.com/Ellipse.html
