Advanced Algebra Nomograph
Read the Fine Print
Rating
0.0 stars
Overview:

This activity is similar to the idea of a function machine. There are two levels of the manipulative (called a nomograph). The first is comprised of two vertical number lines, input on the left and output on the right. The second has three number lines to accommodate displaying the composition of two functions. At the first level, students try to find the rule of a hidden function by entering domain values and observing how they are transformed to new (range) values. The transformation is illustrated dynamically by an arrow that connects a domain entry to its range value. At the second level, students investigate composite functions. Inverse functions are treated as special cases of composition.
