Is the binomial a factor of the polynomial function f(x)=x^3+2x^2-16x-32

GREYUIT [131]

Step-by-step explanation:

f ( 4 ) = 64 + 32 - 64 - 32 = 0

Thus x - 4 is a factor

Find other factors by synthetic division.

"""""""|1"""""2""""- 16"""""-32

"""""4|"""""""4""""""24""""""32

"""""""|1"""""6"" """""8""""""0

( x - 4 ) ( x ² + 6x + 8 ) = 0

( x - 4 ) ( x + 4 ) ( x + 2 ) = 0

x = - 2 , x = - 4, x = 4

You want to buy a pet rabbit that costs $49. You already have $18 and you plan to save $9 per week. If w represents the numbe

kap26 [50]

18 + 9x = 49

with the use of an equation you can easily find out if 6 weeks of saving up is enough to get the rabbit.

18 + 9(6) $\neq$ 49

9 x 6 = 54

54 + 18 = 72

you could have enough money in 4 weeks

The table shows a linear function. <br>which equation represents the function?

Bas_tet [7]

Answer:

Option C is correct.

The equation $f(x)= -\frac{1}{2}x +4$ represents the function.

Step-by-step explanation:

Using slope intercept form to find the equation of line :

For any two points $(x_1, y_1)$ and $(x_2, y_2)$ the equation of line is given by:

$y -y _1 = m(x-x_1)$ ......[1] ;where m is the slope given by:

$m = \frac{y_2-y_1}{x_2-x_1}$

Consider any two points from table :

let (4, 2) and (0, 4) be any two points.

calculate slope:

$m = \frac{y_2-y_1}{x_2-x_1}= \frac{4-2}{0-4}$

$m = \frac{2}{-4} = -\frac{1}{2}$

Now, substitute in equation [1] we have:

$y - 2 = -\frac{1}{2} (x-4)$

Distributive property i.e, $a\cdot (b+c) = a\cdot b + a\cdot c$

$y -2 = -\frac{1}{2}x +2$

Add both sides 2 we get;

$y -2+2 = -\frac{1}{2}x+2+2$

Simplify:

$y = -\frac{1}{2}x+4$

Since, y= f(x)

$f(x)= -\frac{1}{2}x +4$

therefore, the equation $f(x)= -\frac{1}{2}x +4$ represents the function.
