Year 9In this section, students will be exposed to harder quadratic problems including maximum and minimum problems which require knowledge in graphing parabolas. Further concepts like plotting points on graphs, problem solving using quadratics and using different methods for different questions will all be thoroughly explored in the Year 9 Program Guide.

monic: Having the coefficient of the term of highest degree equal to one
pronumeral: A variable is a symbol that stands for a value that may vary; the term usually occurs in opposition to constant
axis: a central line that bisects a two-dimensional body or figure
