Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 2, and the given zeros. -

Musya8 [376]

Answer:

A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;

f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x

Step-by-step explanation:

The given parameters of the polynomial are;

The leading coefficient of the polynomial = 2

The zeros of the polynomial = -4, 0, 2, 4

We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)

For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'

To have a leading coefficient of 2, we can add '2' as a factor of the polynomial

Therefore, we can have the factors of the polynomial as follows;

(x² - 4²)·2·x×(x - 2) = 0

From the above equation, using a graphing calculator, we get the following possible polynomial;

(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0

Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.

Which equation represents the relation that is shown in the graph?

Lapatulllka [165]

Answer:

Step-by-step explanation:

First let's notice a couple things:

All the answers are in y = mx + b form
Two of the answers don't have a value for b
Pretty much all of the answers have a different m value

So let's go in order of our realizations.

Let's start with figuring out what b is. By simply looking at the graph, we can see that b = 0, because the line starts at (0, 0). Remember that b is when the line crosses the y axis, and our y value at x = 0 is 0.

This crosses out A and B.

Now let's find m, aka the slope. We can figure this out using the slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\m=\frac{14-7}{4-2} \\m=\frac{7}{2}$

Awesome! So we've figured out that m = 7/2. This means our answer has to be D.
