Reflection: Got zeros? Polynomials do! Multiplicity of Zeros (Day 3 of 3) - Section 3: Calculator Investigation: Multiplicity of Zeros


As students started attempting question 8 and were asked to write the equations of the polynomial in factored from the graph, I realized that some of my students did not recall what the difference was between standard form and factored form of a polynomial. Here’s what I added to supplement their learning here: Got zeros day 3, video reflection, factored v. standard form.

Got zeros? Polynomials do! Multiplicity of Zeros (Day 3 of 3)

Unit 2: Polynomial Functions and Equations
Lesson 7 of 15

Objective: SWBAT• Determine the degree of the polynomial functions and the effect the degree has upon the end behavior of the functions. • Write possible equations for a polynomial function, given information about its zeros. • Write the equations in factored form, given the graphs of three functions.

Big Idea: Using Nspire Calculators, students investigate the relationships of polynomial functions, their degree, end behaviors, zeros and x-intercepts.
