The curve has a minimum point \(A\).
  1. State the coordinates of \(A\).
  2. A sequence of transformations is applied to the curve in the following order. Translation of 2 units in the negative \(y\)-direction
    Reflection in the \(x\)-axis
    Find the equation of the new curve and determine the coordinates of the point on the new curve corresponding to \(A\).
