PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

<h2>For x=2</h2>

$- 10(2) + y = 4$

$- 20 + y = 4$

$y = 24$

<h2>For x=1</h2>

$- 10( 1) + y = 4$

$- 10 + y = 4$

$y = 14$

<h2>For x=0</h2>

$- 10(0) + y = 4$

$0 + y = 4$

$y = 4$

<h2>For x=-1</h2>

$- 10( - 1) + y = 4$

$10 + y = 4$

$y = - 6$

<h2>For x=2</h2>

$- 10( - 2) + y = 4$

$20 + y = 4$

$y = - 16$

1. determine if the functions are inverse functions

kirill115 [55]

Answer:

<u>Question 1</u>

The function $f(x) = x + 6$ is one-to-one, so it does have an inverse.

The inverse of +6 is -6, so $f^{-1}(x)=x-6$

Therefore, g(x) is the inverse of f(x).

<u>Question 2</u>

The function $f(x) = -3x -9$ is one-to-one, so it does have an inverse.

To find the inverse, replace f(x) with y:

$\implies y = -3x -9$

Rearrange the equation to make x the subject:

$\implies y+9= -3x$

$\implies x=-\dfrac13(y+9)$

$\implies x=-\dfrac13y-3$

Replace x with $f^{-1}(x)$ and y with x:

$\implies f^{-1}(x)=-\dfrac13x-3$

Therefore, g(x) is the inverse of f(x).
