This problem may also be modelled using CabriJr on the TI-83/84 series calculator. Click on the graphic below to download the file and try it yourself! Try having students work in pairs: one generating data points using the CabriJr model and the partner entering these into lists to plot and then to help build their algebraic model! |
Just wait until you try this with TI-nspire CAS! And you may want to have a look at Geometry Expression. |
