If as less than 0, then we set as = 0 in which case if xi greater than xs, that is when minimum is on the left side of the data point, we proceed in the same way as we did in case xi less than xs except that: quadratics S1 and S2 swap their domains of definition.

We now move to quadratics; why then do students experience difficulty in factoring quadratics?
Further topics covered include linear equations in one variable, in two variables, and their associated graphs; simultaneous linear equations; functions and their graphs; linear functions and alternatives to proportional reasoning; linear inequalities and their graphs; exponents; and quadratic functions and their graphs.
