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. The cross sections of microwave transmitters and receivers are parabolic in shape.
