Match the one-to-one functions with their inverse functions.

Nady [450]

The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function
$f(x)= \frac{x}{8} -7$
the inverse of the function is obtained as follows:
$y= \frac{x}{8} -7 \\ \\ y+7=\frac{x}{8} \\ \\ x=8(y+7) \\ \\ \bold{f^{-1}(x)=8(x+7)}$

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:
$y=x+7 \\ \\ x=y-7 \\ \\ \bold{f^{-1}(x)=x-7}$

Given the function
$f(x)=1- \frac{x}{3}$
the inverse of the function is obtained as follows:
$y=1- \frac{x}{3} \\ \\ -\frac{x}{3} =y-1 \\ \\ x=-3(y-1) \\ \\ \bold{f^{-1}(x)=-3(x-1)}$

Given the function
$f(x)=20-0.25x$
the inverse of the function is obtained as follows:
$y=20-0.25x=20- \frac{1}{4} x \\ \\ \frac{1}{4} x=20-y \\ \\ x=4(20-y) \\ \\ \bold{f^{-1}(x)=4(20-x)}$

What is 8 is increased to 22

SOVA2 [1]

<span><span>1. </span>What is 8 increased to 22.
I believe you want me to show you what is the interest increased from 8 to 22
Let’s start the solution process:
=> 8 is the original number and supposed to be the 100% value
=> 22 is the increased number
subtract 22 by 8 to know how much is added.
=> 22 – 8 = 14
=> 14 / 8 = 1.75
=> 1.75 * 100% = 175%
Thus, the added increased is around 175% of the original money</span>

The sequence an = one third (3)n - 1 is graphed below: Find the average rate of change between n = 3 and n = 4.

defon

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}
\\\\\\
\begin{cases}
x_1=3\\
x_2=4
\end{cases}\implies \cfrac{f(4)-f(3)}{4-3}\implies \cfrac{9-3}{4-3}\implies \cfrac{6}{1}\implies 6$

If f(x)= 3x-9 and g(x)= x^2, what is (g0f)(5)

melamori03 [73]

We are asked to find z = g0f or what is the same:
z = g (f (x))
That is, we must introduce the function f (x) within the function g (x)
So, we have
f (x) = 3x-9
g (x) = x ²
Therefore we have the following function
z = (3x-9) ²
Finally (g0f) (5) = (3 (5) -9) ²
(g0f) (5) = 36
