Product Description
This activity will help students use graphing calculators to find the zeros of polynomials.

Includes both teacher and student instructions, 2 student help pages, a student answer sheet and an answer key.

For Algebra 2 or PreCalculus

There are 4 pages for this sort:
~Equations (Degree = 2, 3, 4)~
~Equation in Standard Form (written in y = format)~
~Calculator Screen Shots~
~Zeros of functions~

There are several ways to use the sort
Version 1: Rewriting, graphing, and finding zeros
Students should pick an equation, rewrite the equation to standard form, graph the equation on their graphing calculator. Then change to viewing window to match one of the calculator screen shots. Next they should find the zeros for the function.
Note: A student answer sheet is provided for this method.

Version 2: Rewriting Functions to Standard Form
Students should pick an equation, rewrite the equation to standard form

Version 3: Graph the entire graph
Students should pick an equation and manipulate the viewing window until they can see all the intercepts and extrema. For varying difficulty, some of the provided graphs have the scale changed.
Note: a printable student help page with graphics is provided.

Version 4: Finding Zeros of a function
Students should pick an equation, graph on their calculators, then locate and identify all zeros (or x-intercepts)
