【题目】Find the maximum number o f turning points o f each polynomial function.$$ f ( x ) = - ( x - 1 ) ^ { 2 } ( 1 + 2 x ^ { 2 } ) $$ 相关知识点: 试题来源: 解析 【解析】 $$ f(x)=-(x-1)^{2}(1+2x^{2}) $$ Tirst,identify the teading tern if the pod...
$$ f(x)=-x^{3}+4x^{3}-3x^{2}+1 $$ First, rewrite the polynomial function in descend ing order:$$ f(x)=4x^{3}-x^{3}-3x^{2}+1 $$ Idontify the degree of the polyromial function. This poly nomial function is of degree 5. The maximum number of turning points is 5-1...
Find the absolute maximum and absolute minimum of the function f(x,y)=xy−7y−49x+343 on the region on or above y=x2 and on or below y=52 Absolute Extrema: We have a polynomial function defined over a region enclosed by a...
Find any relative maximum or minimum points of the given function. {eq}\displaystyle y = -x^3 + x^2 + 8 x + 2 {/eq} Relative Extremes in Polynomial Functions: The relative extrema of a function are maximum or minimum points in a neighborhood of this poi...
So I'm basically writing a script that needs to find the maximum and minimum roots of a three root polynomial, for a range of input values. Then, I want to plot these maximum and minimum roots on a graph to obtain a curve. Now, in the current script I have written it is plotting ...

The global maximisation of the likelihood function is carried out through the computation of the global solution of a multivariate polynomial system using numerical Groebner basis in order to considerably reduce the running time. The novelty of the proposed method is the application of the total ...
Then each log-spectral mean vector is divided into several subband vectors and each subband vector is transformed to the testing condition by a polynomial function. In other words, all the channels of each subband share a polynomial transformation, which can further improve the robustness of ...
Use Lagrange multipliers to find the maximum {eq}z {/eq}-value of the function {eq}f(x,y) = 8x^2 - 4y^2 {/eq} subject to the constraint {eq}8x^2 + 4y^2 = 9 {/eq}. Lagrange Multipliers: We want to maximize a polynomial ...
