Explain whether the graph might represent a polynomial function that has zeros of order 2 or of order 3 ,就是这个问题,
Explain whether the graph might represent a polynomial function that has zeros of order 2 or of order 3 ,就是这个问题,
解释这张图表示的是2次函数为0或者3次函数为0的多项式.
就是做因式分解,然后分析形式
比如(x+1)^2=0就是order of 2
(x+1)^3=0,就是order of 3
再问: 什么叫二次函数为0的多项式,还有是不是要是(x+2)的四次就是 order of 4
再举个例子, y=-(x+4)^2 × (x-1)^2 × (x+2) × (2x-3)
问题是Determine the zreos of each polynomial function. Indicate whether they are of order 1,2ro3
再答: 你的例子里(x+4)^2和(x-1)^2是order 2,(x+2)和(2x-3)是order 1。所以就这个例子而言,它是polynomial of order 2(单选的话),最多可以加上还有order 1,但绝对没有order 3.做这题你只要因式分解,然后找每个因式是几次方,那么order就是这么多。(一般来说还是取最高的order,所以你的例子应该是order 2)
再问: 你之前讲的我听懂了,还有个问题什么是 the zeros of each polynomial function
再答: the zeros of each polynomial function就是使得每个多项式结果为0的那个值
