TImath.com Algebra 2 ©2010 Texas Instruments Incorporated Page 2 Domain & Range Before determining the domain and range of the problems given in the activity, students need to. About the Lesson This lesson involves identifying a set of x-values in both symbols and words, identifying the set of x-values used in generating the function as the domain of the function, and identifying the set of y-values used in generating the function as the range of the function.
Finding the domain and range of a function is one of the best ways to investigate the overall behavior of the function. In basic terms, the domain of a function is the range of possible x values that can be input into it, where x stands in for the independent variable.. On a TI-84 or similar model, it is accomplished by pressing the "Y=" key.. The TI-84 calculator can help identify the domain by graphing the function and using its various built-in tools. Below is a step-by-step guide on how to find the domain using a TI-84 calculator. Step 1: Enter the Function in the Calculator. Turn on the TI-84 calculator by pressing the ON button. Press the Y= button to access the function editor.
