Which function does this graph correspond to?

tiny-mole [99]

ANSWER

The function that the given graph corresponds to is
$f(x) = (x - 2)(x - 1)(x + 1)(x + 2)$

EXPLANATION

The given graph in the attachment has x-intercepts at

$x = - 2 ,x=-1,x=1 \: \: and \: \: x=2$

These are the solutions of the polynomial function represented by the given graph.

We can write all these solutions as factors to obtain,

$x + 2 ,x + 1 ,x - 1 \: \:and \: \: x - 2$

The product of all these factors gives us the function whose graph was drawn.

This implies that,

$f(x) = (x - 2)(x - 1)(x + 1)(x + 2)$

Therefore the correct answer is option C.

What is a cubic polynomial function with zeros 3,3 and -3? show your work.

Brums [2.3K]

Answer:

Cubic polynomial function with zeros 3,3 and -3 is $\mathbf{x^3-3x^2-9x+27=0}$

Step-by-step explanation:

We need to find a cubic polynomial function with zeros 3,3 and -3.

If zeros of polynomial are: 3,3,and -3

we can write:

x=3, x=3, x=-3

We can write:

x-3=0, x-3=0, x+3=0

Now, we can write them as:

(x-3)(x-3)(x+3)=0

Multiplying the terms, we can find the polynomial:

$(x-3)(x-3)(x+3)=0\\(x(x-3)-3(x-3))(x+3)=0\\(x^2-3x-3x+9)(x+3)=0\\(x^2-6x+9)(x+3)=0\\x(x^2-6x+9)+3(x^2-6x+9)=0\\x^3-6x^2+9x+3x^2-18x+27=0\\x^3-6x^2+3x^2+9x-18x+27=0\\x^3-3x^2-9x+27=0$
