Answer:

f^{-1}(x)=4x+20

Step-by-step explanation:

<u>Given</u>

<u />f(x)=\frac{x}{4}-5\\ \\y=\frac{x}{4}-5

<u>Swap x and y and solve for y</u>

<u />y=\frac{x}{4}-5\\ \\x=\frac{y}{4}-5\\ \\x+5=\frac{y}{4}\\ \\4(x+5)=y\\\\y=4x+20

<u>Final answer</u>

<u />f^{-1}(x)=4x+20

Keep in mind that we need to swap the variables because a function and its inverse are symmetrical about the line y=x. See the graph below.

To find your answer you would find the perimeter of the small square which is 28.

You would then find the perimeter of the big square which is 56. 

Next, you subtract 56 from 28 and get 28.  

So the difference is 28 inches.

Hope this helps!!

Therefore, ΔCAF ~ ΔDBF by AA similarity. So, By CPCT

arcAC = arcBD.
