Answer:
y = 2/5x - 5
Step-by-step explanation:
y = 2/5x - 5
(If you go to desmos.com you can graph any equation. It really helps. I'm doing similar things in class, I use it all the time.)
Both x and y equal 2.
2•2=4 + 2•2=4
4+4=8
2+2=4

The inverse function of
is 
Step-by-step explanation:
Inverse of a function:
To find the inverse of a function
, basically, we have to reverse r. We exchange y and x in their positions, and then we have to isolate y.
In your exercise:
![y = \sqrt[3]{x} - 8](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7Bx%7D%20-%208)
Exchanging x and y, we have:
![x = \sqrt[3]{y} - 8](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7By%7D%20-%208)
![x + 8 = \sqrt[3]{y}](https://tex.z-dn.net/?f=x%20%2B%208%20%3D%20%5Csqrt%5B3%5D%7By%7D)
Now we have to write y in function of x
![(x+8)^{3} = (\sqrt[3]{y})^{3}](https://tex.z-dn.net/?f=%28x%2B8%29%5E%7B3%7D%20%3D%20%28%5Csqrt%5B3%5D%7By%7D%29%5E%7B3%7D)

So, the inverse function of
