In this polynomials activity, 9th graders solve and complete 3 different problems. First, they illustrate the x is equal to a given number of a function and determine its multiplicity. Then, students factor the function completely and... Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Although this polynomial has only three zeros, we say that it has seven zeros counting multiplicity. What is a 'zero of multiplicity' and where do the "seven zeros" come from (I know the "7" comes from adding the three exponents, "4", the hidden "1", and "2" in the equation, but why call them zeroes?)? Finding the Zeros of a Polynomial Function A couple of examples on finding the zeros of a polynomial function. Example: Find all the zeros or roots of the given functions. f(x) = 3x 3 - 19x 2 + 33x - 9 f(x) = x 3 - 2x 2 - 11x + 52. Show Step-by-step Solutions

Solve the equations for x. The multiplicity of a root is the number of times the root appears. For example, a factor of (x+5)3 would have a root at x = −5 with multiplicity of 3. coefficient. The graph will at the zero of x = , at the zero of x = , and at the zero of x = . 6. A polynomial with a real zero with multiplicity four and two imaginary zeros must be a degree polynomial. Write a factored form polynomial function f(x) of least degree that has a leading coefficient of 1 with the real zeros shown in the graph. 7. en graph the function.

Pre-Calculus Worksheet Name: _____ Section 2.2 - Polynomial Functions DAY TWO Period: _____ I. Use a graphing utility to graph the function.
If the remainder is zero, then it IS a FACTOR Fundamental Theorem of Algebra The degree of a polynomial is equal to the number of roots/zeros of the polynomial (counting multiplicity). In my discovery activity, my aim is for students to discover the pattern for determining the end behavior of higher degree polynomial functions. In the notes afterwards, my aim is to solidify this knowledge and to teach students how to sketch the graphs of these polynomials by finding their zeros. Pre-Calculus Polynomial Worksheet For #1-4, use the Leading Coefficient Test to determine the end behavior of the graph of the given polynomial function. Then use this end behavior to match the polynomial function with its graph. 1. f (x) 2 x3 x 2x 2. f (x) x6 6x4 9x2 3. a. f (x) x5 5x3 4x 4. f(x) x4 1 b. c. d. 6.1-6.6 Review Worksheet Page 2 of 5 Write a polynomial having the given zeros, first in factored form, then multiply it out and put it in standard form. All four graphs have the same zeroes, at x = –6 and at x = 7, but the multiplicity of the zero determines whether the graph crosses the x -axis at that zero or if it instead turns back the way it came.
With this factored form, you can change the values of the leading coefficient a and the 5 zeros \( z_1, z_2, z_3, z_4 \) and \( z_5 \). You can explore the local behavior of the graphs of these polynomials near zeros with multiplicity greater than 1. Students should continue their work on the Student Handout - Multiplicity_of_Zeros_of_Functions to help answer this. We should also just take a moment to remind students about their mathematical practices they should be focusing on today ( Mathematical Practice 5: Use appropriate tools strategically and Mathematical Practice 7: Look for and ... When a factor is repeated in a function, this results in a zero." In other words: the zero has multiplicity of n, where n is the number of times that zero appears as a factor. Key Concept How Multiple Zeros Affect a Graph If a is a zero of multiplicity n in the polynomial function y = P(x), then the behavior of
Use the slider to change the power of the factor (x+2) in the polynomial function. 1. What happens to the graph of the polynomial at the zero -2 as the multiplicity of the zero increases? 2. What happens to the graph of the polynomial at the zero -2 when the power of the factor (x+2) is even? 3 ... This lesson merges graphical and algebraic representations of a polynomial function and its linear factors. As a result, students will: Manipulate the parameters of the linear functions and observe the resulting changes in the polynomial function. Find the zeros of the polynomial equations by finding the zeros of the linear factors.
