• TI-84 Plus Silver Edition
• TI-84 Plus How Many? (Precalculus)

Students will be presented a situation in which they must use linear programming to determine the optimum production level to maximize profits.
• TI-84 Plus CE
• TI-84 Plus C Silver Edition
• TI-84 Plus Silver Edition
• TI-84 Plus All Systems Go!

Students learn about inverse matrices in the context of encoding/decoding secret messages and then use inverse matrices to solve systems of equations.

• TI-84 Plus Infinite Geometric Series

Students explore infinite geometric series. They will consider the effect of the value for the common ratio and determine whether an infinite geometric series converges or diverges.
• TI-84 Plus Silver Edition
• TI-84 Plus Inverses of Functions

Students explore three ways to find the inverse of a function. First, students graph two scatter plots and find the line of reflection. Then, they will graph a line and use the x- and y-intercepts to create the graph of the inverse.
