In this activity, students will use polynomial regression to develop and assess the fit of equations modeling data. The equation models are then evaluated for reasonableness in their use for extrapolating beyond the given data sets.

Students approach performing the basic operations on the polynomials from a graphical perspective. Given the graphs of two functions, they plot points that lie on the graph of the sum of the functions and draw conclusions about its behavior. Next, they calculate a regression to fit the points they plotted. Finally, they find the sum of the functions algebraically and compare it with the result of the regression.

This activity presents a real-world situation--stacking bricks in a pile--that can be modeled by a polynomial function. Students create a small table to show how the number of bricks relates to the number of rows, and calculate the first, second, and third differences of the data. Next, they use the handheld's statistical calculation functions to perform the correct regression. Finally, they evaluate the model using a variety of methods.

In this activity, students will explore the different transformations of several polynomial functions. First they will use spreadsheet to investigate the changes of the y values as a value is added to or multiplied by the function. Then, students will confirm their conjectures using a minimized slider on a graph page. Several questions at the end of the activity assess students’ understanding of the transformations.
