F(x) = 4x^4 – 2x^3 – 3x^2 + 6x - 9 Find the Zeros Using Descartes' Rule of Signs
Komok [63]

Answer:

So possibilities of zeroes are:

Positive       Negative       Imaginary

   1                    1                   2

   3                   1                   0

Zeroes = -1.4549, 1.2658, 0.34457-1.0503i, 0.34457+1.0503i.  

Step-by-step explanation:

Note: Descartes' Rule of Signs is used to find the signs of zeroes not the exact value.

The given function is

f(x)=4x^4-2x^3-3x^2+6x-9

Degree of polynomial is 4 so number of zeroes is 4.

There are three sign changes, so there are either 3 positive zeros or 1 positive zero.

Now, put x=-x in f(x).

f(-x)=4(-x)^4-2(-x)^3-3(-x)^2+6(-x)-9

f(-x)=4x^4+2x^3-3x^2-6x-9

There is one variation in sign change, so there is 1 negative zero.

So possibilities of zeroes are:

Positive       Negative       Imaginary

   1                    1                   2

   3                   1                   0

Using graphing calculator the zeroes of given function are -1.4549, 1.2658, 0.34457-1.0503i and 0.34457+1.0503i.

When Doris Lessing published The Golden Notebook
ValentinkaMS [17]

There was an error in A.

<h3>What is The Golden Notebook?</h3>

The Golden Notebook is a 1962 book by Doris Lessing, a British author. It investigates mental and societal breakdown, much like her two succeeding books, which Margaret Drabble referred to as Lessing's "inner space fiction" in The Oxford Companion to English Literature. In addition to an extensive investigation of communism and the Communist Party in England from the 1930s to the 1950s, the novel also examines the nascent sexual revolution and women's liberation movements. It also contains anti-war and anti-Stalinist undertones. The Golden Notebook was listed among the top 100 English-language books published since 1923 by TIME magazine in 2005. Other languages that it has been translated into include French, Polish, Italian, Swedish, Hungarian, and Hebrew.
