Graphs HOME | Achievement Objectives | Parabola Graphs | Parabola Questions | Cubics | Hyperbola | Circles | Exponential | Logs | Radians | Trig Graphs Overview | Trig Vertical Shift | Trig Horizontal Shift | Trig Equations | Trig Models | General Translations | Applications | Revision

 

Achievement Standard 2.2 Graphs investigates many more types of graph than covered in level 1 (line & parabola) Link to Standard on NZQA (word doc)
Graphs of equations are sketched, equations formed from given graphs and graphs and equations are used to model practical situations.

Desmos graphing software fantastic!!!
