Ride the Rollercoaster

Updated on

Students 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.

Finding Extraneous Solutions

Updated on

In this activity, students will graphically solve a radical equation. They are given each step of solving the equation. For each step students are to graph each side of the equation as a separate function and find the intersection. Students will determine in which step the extraneous solution appears.

Investigation of End Behavior

Published on

Students use a scenario to begin their investigation of end behavior. In this scenario, students make a prediction about what they think will happen as more football players choose to order pizza. Students will hypothesize that the cost will go down as more players decide to order.

Rational Functions

Published on

Students investigate the graphs of functions of the form y = 1/(x - a). They will discover that the graph of such a function has a vertical asymptote at x = a, and a horizontal asymptote at y = 0. They will investigate the graphic and numeric consequences of such asymptotic behavior by observing a trace point on the graph move in response to various inputs for the independent variable.
