Consider the curve y2=12x.
(i) Prepare a table of values for at least five convenient points on the curve, choosing positive x-coordinates that give integer values of y wherever possible.
(ii) Using the values obtained in part (i), draw a neat sketch of the curve on graph paper and mark clearly the vertex and the axis of the parabola.
(iii) Write the coordinates of the focus and the equation of the directrix of the parabola.
