Which equation is the inverse of f(x)=LaTeX: \frac{1}{x+2}1 x + 2 A. LaTeX: f^{-1}\left(x\right)=\frac{1}{x}+2f − 1 ( x ) = 1 x

inna [77]

Answer:

$g^{-1}x = \frac{1-2x}{x}$

Step-by-step explanation:

Given the function $g(x)= \frac{1}{x+2}$ , we are to find the inverse of the function and this can be done y following the simple steps:

Step 1: Replace y with $g(x)$

$g(x)= \frac{1}{x+2}\\y= \frac{1}{x+2}$

Step 2: Interchange x with y

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

Step 3: Make y the subject of the formula;

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

Step 4: Replace y as $g^{-1}(x)$

$g^{-1}x = \frac{1-2x}{x}$

Hence the inverse of the function is $g^{-1}x = \frac{1-2x}{x}$

Which polynomial is prime?

finlep [7]

we know that

If the only factors a polynomial are $1$ and itself, then that polynomial is prime.

If the polynomial has at least one root (one x-intercept) then the polynomial is not prime

Using a graph tool

case 1)

$x^{3}+ 3x^{2} + 2x+ 6$

see the attached figure N 1

The polynomial has one root-------> the polynomial is not prime

case 2)

$x^{3} + 3x^{2} - 2x - 6$

see the attached figure N 2

The polynomial has three roots-------> the polynomial is not prime

case 3)

$10x^{2}-4x+3x + 6$

$10x^{2} -x + 6$

see the attached figure N 3

The polynomial has zero roots-------> the polynomial is prime

case 4)

$10x^{2}-10x+6x - 6$

$10x^{2} -4x - 6$

see the attached figure N 4

The polynomial has two roots-------> the polynomial is not prime

therefore

the answer is

$10x^{2}-4x+3x + 6$ ------> is prime
