# 2.2 Graphical methods to solve Problems AS 91257

 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!!! Activity Match Graph & Function (www.transum.org)
