Understand the concept of odd multiplicity and how it affects the graph of a polynomial function.how to find the multiplicity of zerosLearn how to find and interpret the zeroes and multiplicities of a polynomial function from its graph. Odd-multiplicity zeroes cross the x-axis, while even-multiplicity zeroes touch it.odd multiplicityLearn how to identify zeros and multiplicity of polynomial functions with even and odd powers. See how the graph behavior at x-intercepts depends on the multiplicity and the degree of the polynomial.If the exponent on a linear factor is odd, its corresponding zero has odd multiplicity equal to the value of the exponent, and the graph will cross the -axis at this zero. The sum of .Learn how to identify odd multiplicity of zeroes from the graph of a polynomial, and how to use this information to find the degree and the polynomial. See examples, .

odd multiplicity how to find the multiplicity of zeros Given the graph of a polynomial and looking at its x-intercepts, we can determine the factors the polynomial must have. Additionally, we can determine whether those factors are raised to an odd power or to an even power (this is called the multiplicity of .If f ‍ has a zero of odd multiplicity, its graph will cross the x ‍ -axis at that x ‍ value. If f ‍ has a zero of even multiplicity, its graph will touch the x ‍ -axis at that point. Look at the graph of the function \(f\) in Figure \(\PageIndex{2}\). Notice that, at \(x =−3\), the graph crosses the x-axis, indicating an odd multiplicity (1) for the zero \(x=–3\). Also note the . Since \(1\) is an odd number, we know from Theorem 3.3 that the graph of \(f\) will cross through the \(x\)-axis at \(\left(\frac{1}{2},0\right)\). Since the zero \(x=-1\) corresponds to the .

the zero $\,0\,$ has multiplicity $\,4\,.$ Here's the shortcut: solve ‘$\,-x = 0\,$’ to get the zero; assign the power as the multiplicity.

答案是odd multiplicity. 我不理解。. 追答. 那就应该不是这个意思了，是这个意思：. Let f(x) be a polynomial function. Then, if f is graphed on a Cartesian coordinate system, its graph will cross the x-axis at real zeros of odd multiplicity and will touch but not cross the x-axis at real zeros of even multiplicity.

The multiplicity of a zero of a polynomial is the degree of the corresponding factor; if there is a factor (x − a)m, then we say that a is a zero of multiplicity m. When the multiplicity is 1, the graph crosses . List the zeros of P, together with their multiplicities. Solution: Since (3x−5)7 = [3(x− 5 3)]7 = 37(x− 5 3)7 the zero 5 3 has multiplicity 7. You don't need to go through all this work: just solve 3x−5= 0 to get the zero; assign the power as the multiplicity. Since (−x)4 = (−1)4x4 = x4. the zero 0 has multiplicity 4.

The next zero occurs at [latex]x=-1\\[/latex]. The graph looks almost linear at this point. This is a single zero of multiplicity 1. The last zero occurs at [latex]x=4\\[/latex]. The graph crosses the x-axis, so the multiplicity of the zero must be odd. We know that the multiplicity is likely 3 and that the sum of the multiplicities is likely 6. Notice that, at \(x =−3\), the graph crosses the x-axis, indicating an odd multiplicity (1) for the zero \(x=–3\). Also note the presence of the two turning points. This means that, since there is a \(3^{rd}\) degree polynomial, we are looking at the maximum number of turning points. So, the end behavior of increasing without bound to the .We call this a triple zero, or a zero with multiplicity 3. For zeros with even multiplicities, the graphs touch or are tangent to the x-axis at these x-values. For zeros with odd multiplicities, the graphs cross or intersect the x-axis at these x-values. See the graphs below for examples of graphs of polynomial functions with multiplicity 1, 2 .
