Older students can model and extrapolate the data with a quadratic, exponential or inverse function using our Excel file or our Desmos graph. This data is from the 2013 draft. You might ask students to predict what the graph of the 2014 or 2015 contracts might look like. How will it look similar or different from the 2013 graph?
