11 The diagram shows the parabola, \( \mathrm{f}(x) \), and the straight line, \( \mathrm{g}(x) \). Points \( A, B, C \) and \( D \) are the intercepts on the axes.
\( E \) is the point of intersection of the two graphs.
(a) \( D \) is the image of \( B \) after \( B \) has been translated two units to the right:
Write the co-ordinates of point \( D \).
Answer (a) ( \( \qquad \)
