Objectives
Students practice generating quadratic equations. Two methods are used, one uses axis intercepts (factorised form) and dilation (using y axis intercept) the other technique is the transformed function (turning point) and dilation (point on the curve). In addition to practicing these techniques, students gain a better understanding of the modelling process.
Vocabulary
- Factors and axis Intercepts
- Turning point and Turning point form
- Dilation factor
- Modelling
- Subtraction of ordinates
About the Lesson
Students orientate the cartesian plane into an appropriate location so they can generate a variety of equations to model the iconic Sydney Harbour bridge. Students use a range of techniques, the image provides direct feedback to students regarding their calculations.
