A straight line y=3x+c and the parabola y=x2 bound a region between x=0 and x=3.
(i) State the inequality that c must satisfy so that the line remains above the parabola for every x in [0,3].
(ii) Derive an expression, in terms of c, for the area of the region enclosed by the two curves on [0,3].
(iii) Given that this area equals 27 square units, determine the value of c.
