  1. Write down the equations of the two asymptotes.
  2. The points on the hyperbola for which \(x = 4\) are denoted by \(A\) and \(B\). Find, in surd form, the \(y\)-coordinates of \(A\) and \(B\).
  3. The hyperbola and its asymptotes are translated by two units in the positive \(y\) direction. Write down:
    1. the \(y\)-coordinates of the image points of \(A\) and \(B\) under this translation;
    2. the equations of the hyperbola and the asymptotes after the translation.
