Multiplicity Of 3 Math
The eleventh degree polynomial x 3 4 x 2 7 has the same zeroes as did the quadratic but in this case the x 3 solution has multiplicity 4 because the factor x 3 occurs four times that is the factor is raised to the fourth power and the x 2 solution has multiplicity 7 because the factor x 2 occurs seven times.

This factor is cubic degree 3 so the behavior near the intercept is like that of a cubic with the same s shape near the intercept as the function latex f left x right x 3 latex. Problems for each function find the roots and their corresponding multiplicity. One of the main take aways from the fundamental theorem of algebra is that a polynomial function of degree n will have n solutions. Multiplicities 4 cool math has free online cool math lessons cool math games and fun math activities.
The one remaining root the zero at x 1 must be the zero of multiplicity 3. This matches the graph since the line goes through the axis but flexes as it does so telling me that the multiplicity must be odd and must be more than 1. 1 f x x 2 5x 6. The graph passes through the axis at the intercept but flattens out a bit first.
The notion of multiplicity is important to be able to count correctly without specifying exceptions for example double roots counted twice. In mathematics the multiplicity of a member of a multiset is the number of times it appears in the multiset. So if we have a function of degree 8 called f x then the equation f x 0 there will be n solutions. It means that x 3 is a zero of multiplicity 2 and x 1 is a zero of multiplicity 1.
How many times a particular number is a zero for a given polynomial. The polynomial p x x 1 x 3 is a 3rd degree polynomial but it has only 2 distinct zeros. For example the number of times a given polynomial equation has a root at a given point is the multiplicity of that root. We call this a triple zero or a zero with multiplicity 3.
For example in the polynomial function f x x 3 4 x 5 x 8 2 the zero 3 has multiplicity 4 5 has multiplicity 1 and 8 has multiplicity 2. The solutions can be real or imaginary or even repeated.
