find the equation of a parabola that has a vertex of (-2,-3) and contains the point (4,1).

  1. Reiny

    you already know the equation must be

    y = a(x+2)^2 - 3
    All that is missing is the value of a

    To find a, plug in the given point and solve for a.
    Rewrite my equation and you are all done.
