Form a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3

polet [3.4K]

The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is $x^3-3x^2-x+3=0$

Step-by-step explanation:

We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.

If -1, 1 and 3 are real zeros, it can be written as:

x= -1, x= 1, and x = 3

or x+1=0, x-1=0 and x-3=0

Finding polynomial by multiply these factors:

$(x+1)(x-1)(x-3)=0\\(x+1)(x(x-3)-1(x-3))=0\\(x+1)(x^2-3x-x+3)=0\\(x+1)(x^2-4x+3)=0\\x(x^2-4x+3)+1(x^2-4x+3)=0\\x^3-4x^2+3x+x^2-4x+3=0\\Combining\,\,like\,\,terms:\\x^3-4x^2+x^2+3x-4x+3=0\\x^3-3x^2-x+3=0$

So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is $x^3-3x^2-x+3=0$

Sonbull [250]

Answer:

F(x) = 6x + 5.

Step-by-step explanation:

Given that :

Number of cards Given to Sébastian = 4

Number of baseball cards purchased every month = 6 cards

Number of months = x

Linear function f(x) which shows the number of cards after a number of months:

(Number of cards produced per month * Number of months) + number of card `

F(x) = 6x + 5

The mean weight of four trucks were 3,700 pounds.The first truck was 3,250 pounds.The second truck was 3,890 pounds.Tue lady tru

9966 [12]

Answer:

4,020

Step-by-step explanation:

mean = average

Ideally, in order for us to have a 3,700 pound average, each of the four trucks would be 3,700 pounds. Added up, we would have a total of: 14,800 pounds (3,700×4)
Let's see how much pounds we already have:
3,250 + 3,890 + 3,640 = 10,780

Now we need to find how much pounds we are missing: 14,800 - 10,780 =

<h2>4,020 for the fourth truck</h2>

Let's check: 3,250 + 3,890 + 3,640 + 4,020 = 14,800
14,800/4 = 3,700 pounds

<h3>Good job! I hope this helps</h3>
