Is (x+7) a factor of f(x) x3-3x2+ 2x-8?

Snowcat [4.5K]

Answer:

(x+7) is not a factor

Step-by-step explanation:

we know that

If (x+7) is a factor of f(x)

then

For $x=-7, f(-7)=0$

Verify

we have

$f(x)=x^{3}-3x^{2} +2x-8$

Substitute x=-7

$f(-7)=(-7)^{3}-3(-7)^{2} +2(-7)-8$

$f(-7)=-343-147 -14-8$

$f(-7)=--512$

$-512\neq 0$

therefore

(x+7) is not a factor

Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

I need help please help me

rusak2 [61]

Answer:

Ok,You need to put the value of x that appears in the table to give you the result of h (x)

1.h(x)=4x+5

h(-5)=4(-5)+5

h(-5)= -20+5

h(-5)= -15

2.h(-1)=4(-1)+5

h(-1)= -4+5

h(-1)= 1

3. h(1)=4(1)+5

h(1)=4+5

h(1)=9

4. h(3)=4(3)+5

h(3)=12+5

h(3)=17

5. h(4)=4(4)+5

h(4)=16+5

h(4)=21

Step-by-step explanation:

x h(x)

-5 -15

-1 1

1 9
