6E: sketching cubic graphs in the form f(x)=a(x-h)^3+k and its inverse graph y=x^1/3
objective: to recognise the general equation of cubic graphs where a is the dilation factor from the x-axis and (h,k) is the point of inflection

6G- cubics inequalities
objective: able to sketch three types of cubic functions, and solve the inequalities equation.
6D:solving cubics equations
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
