Quadratic Graphs

Graphs are used to display or model the relationships between real life variables when analysing experimental data.

Linear graphs are used when there is a clear straight line relationship and when it is sufficient to determine the 'general trend', but when the relationship is a curve a quadratic graph may be more accurate.

Quadratic Graphs are commonly called parabolas. You will need to revise Quadratic Equations before beginning this section.
