Show by substitution that the curves intersect at three points whose 2 x-values are -4, 1 and 2. ii) On the same number plane, using geogebra online or sketch the 4 graphs of the parabolas y = x3 - 3 and y = -x2 + 10x - 11, clearly indicating their points of intersection. Shade the region enclosed between them iii) Find the area of the region bounded by the two curves. 4
