Write an equation for the cubic polynomial function whose graph has zeroes at 2, 3, and 5.

TiliK225 [7]

we know that

For a polynomial, if x=a is a zero of the function, then (x−a) is a factor of the function. The term multiplicity, refers to the number of times that its associated factor appears in the polynomial.

In this problem

If the cubic polynomial function has zeroes at 2, 3, and 5

then

the factors are

$(x-2)\\ (x-3)\\ (x-5)$

Part a) Can any of the roots have multiplicity?

The answer is No

If a cubic polynomial function has three different zeroes

then

the multiplicity of each factor is one

For instance, the cubic polynomial function has the zeroes

$x=2\\ x=3\\ x=5$

each occurring once.

Part b) How can you find a function that has these roots?

To find the cubic polynomial function multiply the factors and equate to zero

$(x-2)*(x-3)*(x-5)=0\\ (x^{2} -3x-2x+6)*(x-5)=0\\ (x^{2} -5x+6)*(x-5)=0\\ x^{3} -5x^{2} -5x^{2} +25x+6x-30=0\\ x^{3}-10x^{2} +31x-30=0$

therefore

the answer Part b) is

the cubic polynomial function is equal to

$x^{3}-10x^{2} +31x-30=0$

What is -6 -8 -10 -5 -2 -3 -1 from least to greatest?

WINSTONCH [101]

Answer:

-10, -8, -6, -5, -2, -1

Step-by-step explanation:

I knew this because every negative number can still relate to being the least number. But hey, hope this helps. :]

the number of bacteria in a sample after x days is represented using the equation <img src="https://tex.z-dn.net/?f=b%3D50%2C000

KATRIN_1 [288]

Initial, x = 0, b = 50000

day 1, x = 1, b = 50000 (1.05)^-1

day 2, x = 2, b = 50000 (1.05) =^-2

day 2 / day 1 = 1.05^-2 / 1.05^-1 = 1.05^-1 = 0.952

Which means that the number of bacteria decreased 4.8%
