A powerpoint with worksheets on the profit parabola model. A nice rich task to use with high-ability GCSE students, to deepen their understanding of quadratic functions/maximum points and also to see a real-life application of maths.

The axis of the parabola is the positive x-axis. Similarly, we can derive the equations of the parabolas in the other three figures (Fig. 2) as: (b): y 2 = – 4ax, (c): x 2 = 4ay, (d): x 2 = – 4ay. These four equations are the Standard Equations of Parabolas. Observations. A parabola is symmetric with its axis.
