The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, x = 2, has multiplicity 2 because the factor (x − 2) occurs twice. The x -intercept −1 is the repeated solution of factor (x + 1)3 = 0.

What is the sum of the multiplicities?
Identify zeros of polynomial functions with even and odd multiplicity. Graphs behave differently at various x -intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Demonstrates how to recognize the multiplicity of a zero from the graph of its polynomial. Explains how graphs just "kiss" the x-axis where zeroes have even multiplicities.
Polynomial functions are functions that term or terms that may contain different components, including variables, constant, and exponents. Try to think of different combinations, and you’ll realize that polynomial functions cover a wide number of functions.

A polynomial function is a function that can be expressed in the form of a polynomial. The definition can be derived from the definition of a polynomial equation. A polynomial is generally represented as P(x). The highest power of the variable of P(x) is known as its degree. Degree of a polynomial function is very important as it tells us about the...
There are various types of polynomial functions based on the degree of the polynomial. The most common types are: 1. Constant Polynomial Function: P(x) = a = ax0 2. Zero Polynomial Function: P(x) = 0; where all ai’s are zero, i = 0, 1, 2, 3, …, n. 3. Linear Polynomial Function: P(x) = ax + b 4. Quadratic Polynomial Function: P(x) = ax2+bx+c 5. Cubi...
The graph of P(x) depends upon its degree. A polynomial having one variable which has the largest exponent is called a degree of the polynomial. Let us look at P(x) with different degrees.
Q.1: What is a Polynomial? A polynomial is defined as an expression formed by the sum of powers of one or more variables multiplied to coefficients. In its standard form, it is represented as: an xn + an-1 xn-1+.……….…+a2 x2 + a1 x + a0 where all the powers are non-negative integers. And, a0,a1,………,an ∈ R A polynomial is called a univariate or multi...

Given a graph of a polynomial function of degree n, n, identify the zeros and their multiplicities. If the graph crosses the x -axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x -axis and bounces off of the axis, it is a zero with even multiplicity.
The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, [Math Processing Error] x = 2, has multiplicity 2 because the factor [Math Processing Error] ( x − 2) occurs twice.
