In this activity, students explore discontinuities on function graphs using the TI-84 Evo. Through guided examples and problems, students investigate vertical asymptotes, removable discontinuities (holes), jump discontinuities, and other essential discontinuities — described both graphically and using limit notation. The TI-84 Evo's POI and Asymptote detection trace features serve as hands-on tools to visualize and classify these breaks across a variety of function types.

In this activity, students explore Points of Interest (POI) on function graphs using the TI-84 Evo's built-in Detect POI trace feature. Starting with key graphical features — zeros, y-intercepts, maxima, minima, and intersections — students use the POI trace tool to identify these features dynamically as they trace along function graphs. The activity then extends into calculus, where students investigate the relationships between a function's points of interest and those of its first and second derivatives.

In this activity, students explore the effects of additive and multiplicative transformations on the sine function using the TI-84 Evo's Transformation Graphing App. By dynamically adjusting the constants A, B, C, and D in f(x) = A sin(B(x + C)) + D, students investigate how each parameter affects amplitude, period, phase shift, and midline, before applying their understanding through a summary and practice exercises.

In this activity, students use the Polynomial Root Finder App on the TI-84 Evo to find the zeros of polynomial functions, including those with real, irrational, and complex roots. Students explore how the Fundamental Theorem of Algebra and the Principle of Zero Products can be applied to factor polynomials and identify their zeros. The activity also engages students in analyzing the behavior of polynomial graphs near their real zeros and using sign charts to solve polynomial inequalities.

In this activity, students will explore how a pendulum moves by placing a pendulum bob directly across from a CBR™ 2 motion sensor. Distance and time data are collected for several swings. The graph of the data can be modeled by a sinusoidal function.

In this activity, students will use the Transformation Application to change the values of parameters in trigonometric functions and to determine the effect that each change has on the shape of the graph. Students will then use this knowledge to write equations for sine and cosine functions.
