In this activity, students will use sliders to examine how the square root function is transformed on the coordinate plane. As an extension, students will examine similar transformations on a cube root function.

This activity is based on an impact study to address the concerns of the residents of a community near an airport. Students perform a simulation to measure the sound intensity at different distances from the source of the noise, and then use the data to develop an inverse variation model. After verifying the model, students use it to map safe and unsafe zones based on sound-intensity restrictions.

Students build a solution to a rather complex problem: Finding the edge length of an octahedron given its volume by solving two simpler problems first. First, they find a formula for the edge length of a square given its area. Then students find, test, and apply a formula for the edge length of a cube given its volume.

In this activity, students will solve radical equations graphically. Several square and cubic root equations are given for students to graph and find intersections with the x-axis. Students will also use the distance formula to solve an extension problem.

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.
