Answer:

X <u><</u> 5

Step-by-step explanation:

So when they say 'no more than' its basically like 'less than or equal to' which means that it could be less than 5 or equal to 5 but just be careful when the question says 'at least' because that means 'greater than or equal' so here you could write a number that's greater than (number) or equal to (number)

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).
