Objectives: similar to ex 6C, we need to factorise the cubic equation and apply the Null Factor Law learned in chapter 3-Quadratics. Case 1: factors form. Use Null factor loaw Case 2: groupings- factorise the first two terms, factor out the common factor, and finally null factor law case 3: apply factor theorem, long division, cross method and finally null factor law
objectives: given a graph, find the equation of the cubic function. given an equation with unknowns 'a' and 'b' and a point (x,y), find the equation. click on the link to explore these cubic graphs y=ax^3 y=a(x-h)^3 +k y=a(x-b)(x-c)(x-d) y=ax^3+bx^2+cx+d y=a(x-b)(x-c)^2 question 9a) question 2
