This activity combines both algebraic and graphical representations of transformations of any parent graph. The students are required to view an algebraic equation, list its parent graph, describe its transformations, and then graphically represent the equation by showing both the parent graph and its final transformation. It is a very flexible activity that can be easily edited.

Teacher will use the TINavigator™ to submit graphs of absolute value functions and students will attempt to match the teacher graphs while logged on to TINavigator. Several questions are suggested to help students analyze the functions and internalize their understanding.

The activity uses Cabri Jr. and TINavigator™ to explore the angle between the branches of an absolute value function. By the end of the activity, absolute value functions will be connected to trigonometry. This activity can be used in an algebra 2/precalculus course where students are already familiar with absolute value and trigonometric functions. It can also be used to introduce students to the connections between functions in an algebra 1 or geometry course.

Students use a nomograph, or type of function machine, to determine the rule of several functions by entering values of x and observing how the value of y changes.

This activity is similar to a function machine. The nomograph is comprised of two vertical number lines, input on the left and output on the right. The transformation of input to output is illustrated dynamically by an arrow that connects a domain entry to its range value. Students try to find the rule of hidden functions by entering different domain values. They also use a nomograph with three vertical number lines to explore composite functions, including the composition of inverse functions.

Students simulate the process a surveyor would use to measure the width of a river by measuring length on one side of the river and angles formed by various reference points. They then prove the Law of Sines and apply it to calculate the river's width, proving that no river is too wide to be measured with trigonometry.
